I have been having this minor problem for years, with the Windows Nextcloud client (V.14) I keep getting intermittently a pop-up saying Action Required.
I have tried in vain to figure out what action is required, not found anything I can see missing, or any explanation of what action is required. Is there a way to see why this keeps popping up, I would rather not disable all notifications from Nextcloud, but having two or three dozen pop-ups a day for nothing basically means I ignore them. Sooner or later I will ignore a pop-up that I should be paying attention to.
Thanks in advance
