Hi all...so, not sure what is going on. I have been working on a course. I've revised it, saved it after making changes, etc. However, each time I save and close down, when I reopen the document, much of the formatting has changed...in fact, been lost...mostly the player and course properties. Some of the engage interactions that were clearly part of the course are now not there, but exist elsewhere, and I have to republish them into the course. I recently upgraded using recent upgrades, but it still seems to be quirky. What is going on?
