I don’t know how the workaround works, I just concluded that there has to be a working solution as other sync tools can synchronize where DAVx5 fails. I will try to see if I can provide more input to help you diagnose the problem, but it may take some time…
ready for Android Q
basic support for day/night theme (dark theme when set by system)
fix that outdated error message doesn’t disappear when entering calendar URL
support Autofill (password managers) for credentials
new translations (thanks for PT-rBR)
You didn’t enter a port. You will probably have to use the port of your CalDAV server, i.e. https://<quickid>.fr2.quickconnect.to:<port number>/caldav/<account_name>
Ah. I didn’t address the moving window part. All I can think is sent data includes a scankey code to Grab Window. I use XFCE and it has ALT + Right-Mouse-Drag to move a window. I’m not sure how that would be fixed.
Additionally, while you are frustrated, try to refrain from cursing or swearing when asking for help.
