Here is a reply I got about a year ago from TI

For learners, we support the current and the previous major release of Chrome, Firefox, Safari, and Microsoft browsers. This currently includes Microsoft Edge. Each time a new browser version is released, we begin supporting that version and stop supporting the third most recent version.For administrators we support the same as above however in Microsoft Edge we have had instances of inconsistencies and unintentional behaviors across different features of the Platform. (Things like Reporting etc)

1. We find it plays nicely only with Chrome. In fact 9 times out of 10 if a user has an error in another browser we find they do not have this issue in Chrome and it is what we recommend. Safari is the only other browser we have used because it works well-ish. 
2. No. We just did a full review of the tablet and phone views of the system and have found it is not necessarily auto-responsive. TI does not have a mobile version but is is supposed to be mobile-responsive and we have found that it is not ideal. I woulld be happy to share some of our findings and research. 

@juliefiretech @grace.filkins It’s not really a Ti thing.  There are many reasons that ChatGPT 4.0 shared with why Chrome works best with online learning.  Here are the reasons it shared.  Reasons Chrome is just the best choice.

Chrome is often the preferred browser for online learning for several reasons:

1. **Compatibility and Support:**
- **Wide Adoption:** Chrome has a large user base, meaning most online learning platforms are optimized for it. This ensures that learners experience fewer compatibility issues.
- **Standards Compliance:** Chrome is highly compliant with modern web standards, ensuring that it can handle the latest web technologies and features used in online learning platforms.

2. **Performance:**
- **Speed:** Chrome is known for its fast browsing speed, which is crucial for smooth and responsive online learning experiences, especially when dealing with multimedia content like videos and interactive elements.
Resource Management:** Chrome effectively manages system resources, making it capable of handling complex web applications without significant slowdowns.

3. **Stability and Reliability:**
- **Frequent Updates:** Google frequently updates Chrome, addressing bugs, security vulnerabilities, and performance issues promptly. This ensures a stable and reliable browsing experience.
- **Crash Handling:** Chrome isolates each tab in a separate process, meaning a crash in one tab doesn't affect the others, reducing disruptions during learning sessions.

4. **Security:**
- **Built-in Security Features:** Chrome has robust security features, including automatic updates, sandboxing, safe browsing, and phishing and malware protection, providing a secure environment for online learning.
- **Privacy Controls:** Chrome offers extensive privacy controls, allowing users to manage cookies, site data, and permissions, enhancing data protection.

5. **Cross-Platform Consistency:**
- **Multiple Devices:** Chrome provides a consistent browsing experience across different devices (desktops, laptops, tablets, and smartphones), ensuring learners can access their courses seamlessly from any device.
- **Sync Features:** Chrome's sync feature allows users to access their bookmarks, history, passwords, and settings across multiple devices, facilitating a continuous learning experience.

6. **Accessibility:**
- **Built-in Accessibility Features:** Chrome includes various built-in accessibility features such as screen reader support, high contrast mode, and keyboard shortcuts, making it easier for learners with disabilities to navigate and use online learning platforms.
 

These factors combined make Chrome a robust, efficient, and user-friendly browser, well-suited to meet the demands of online learning environments.

Thought Industries supports multiple browsers, not just Chrome. The platform supports the current and the previous major releases of the following browsers:

• Chrome
• Firefox
• Safari
• Microsoft Edge

For mobile browsers, the platform supports:

• Current and previous Android versions
• Current and previous iOS versions

This means that while Chrome is supported, other browsers like Firefox, Safari, and Microsoft Edge are also supported and should work well with the platform. Each time a new browser version is released, support for the third most recent version is discontinued, ensuring compatibility with the latest and the previous major releases of these browsers.

​@Philcahill87 when trying to use Safari as a manager I keep getting 401 errors. I have checked settings and not sure what I am missing. Any thoughts?

​@Philcahill87 ​@grace.filkins Safari is naturally more susceptible to this because its privacy policies are more strict than other browsers and this is discussed on the web as well as why Safari is not the preference of Ti.  Check with each update that you are allowing “cross browser tracking” first.  Second is that Safari has very strict redirect policies that but course completion at risk.  If an authenticated endpoint redirects to another domain (e.g., Single Sign-On systems), Safari might drop cookies or headers during the redirect process, resulting in a failed authentication and a 401 error.

There is more.  Safari is strict and you should look up 2025 and how browsing will different.  Chrome wants to single handedly stop all third party cookies.  Guess how SCORM reports back to an LMS? Third party cookies.  Hope this helps.

Thank you ​@charles.zimmerman as always you are a huge help. Do you have a secondary browser you use for any testing?
