I've been having a lag sorta on like edit, etc., with one project. It is/was a project i had in the project folder of the Beta copy. Things were lagging and then some weird stuff i won't try to discribe..
So i created a project in the new release 2022 and moved the drawings there, and so far seems to maybe have fixed the issue. Might have been doing it in 2022 on plans that are still in the
project folder of 2020. It was a very noticable lag.
I did a ticket 66660 for it
