EndNote 21 - slower than 20 (if such a thing is possible!)

Is anyone finding that EndNote 21 is even slower than Endnote 20? Using it on an Office-based system. We’ve just upgraded and it is beyond appalling. I thought 20 was slow and was hoping 21 might be better. Could it be to do with the fact that is it hosted on a cloud-based server? Or perhaps its just not been tested rigourously enough…

I miss the days of EndNote 8, or even Reference Manager.

Not noticeably slower on win10 and win11 for me.
