Yes, I agree, lost memorized reports (Took Some time to create again- Hard way) after upgrading to QB Desktop 2021.

I tried all, nothing can bring those report back. I also sent the feedback at support. Regarding the Resort list, it just sorts the list and that feature does not bring back, what is lost. The Resort should be set to automatic. Why because, Here are the three Steps to lookup Memorized report

1. Reports – Memorized Reports –the list of my Own created reports are NOT in alpha/numeric Sort

2. Reports – report Center- Memorized - the list of my Own created reports are NOT in alpha/numeric Sort

3. Reports – Memorized Reports - Memorized report List -This list is PERFECT in ALPHA/Numeric Order.

Auto Sort on all three places would be Ideal
