I am having the same problem. Editing tags while in a Report is a feature I have used for many years with no issues until recently. Are they working on this new bug?
I have used this feature of editing tags while in a Report for many years and now it does not work. I just finished a chat with Support (March 18, 2023). It is a new bug. They acknowledge that editing tags while in a Report is not working. But would not give any ETA on when it might be fixed.
