Confirm the regression too.
got I9300 with replicant 6.0 0003
Long time ago, add account to davdroid installed from f-droid. Following upgrade from f-droid repository and work well with latest version of Davx5.
But have to reinstall os, reinstall Davx5, and cant register new account with the same stack of error when trying this url: https://domain.tld/baikal/html/dav.php
And when trying https://domain.tld/baikal/html/dav.php/calendars/user/work/, Davx5 print crash popup.
Install an old davdroid apk and work well. Work well with Thunderbird too for calendar and Inverse SOGo Connector for address book. Not a server side problem.
Thanks a lot for this software ! Happy to use it daily.
