There is so much to consider. The only thing that I am certain of is that you would NEVER put an individual session in a Learning Path unless that LP has a short shelf life.
Currently I am adding the Parent/Root/Primary content to the LP but the way ILT is structured, I find it all very confusing. I then select to let the learner chose from any session available. Sometimes this works and sometimes not.
What to do to keep it clean? Are you archiving your past events or just unreleasing them? I would love to do a Zoom and let you share your best practices with me if you are willing. Thanks for the consideration and add what you can here for others who also struggling with ILT in a LP.
