Edits to CC Library yesterday, not there today

I made edits to the CC Library yesterday while I was using InDesign 20.0 2025.

I opened them today in InDesign 19.0 2024 and the edits are not there... I panicked then opened InDesign 20.0 to see if they show up there thinking they are version dependent (scary thought) but they are not there either. (only 2 other designers are able to edit the Libraries)

I have a lot of people using these libraries. What's going on?? How can I prevent this from happening again? How can I retrieve the work I did yesterday?
