As I mentioned in the other thread, I have the same problem:
It first appeared after updating to Enpass 6.8.3 in early October. (The same update also destroyed the Dropbox Sync for me)
I use Safari on macOS.
it seems to help to quit and restart the Enpass app, then the problem goes away until it occurs again at some point.
My Setup:
Intel based iMac
macOS 13.1
Safari 16.2
Enpass 6.8.4 (1166)
