Hello,
after upgrading from Lineage 15 to 16 and upgrading from Davdroid to Davx5 simultaneously I cant sync tasks from my nextcloud anymore. Contacts and calendar events are fine and it also synced the name and colours of my task lists. The actual content, however, was missing. Each attempt to sync would end in a notification of a
java.lang.ClassCastException: net.fortuna.ical4j.model.property.XProperty cannot be cast to net.fortuna.ical4j.model.property.Uid
for each task list.
I fixed my issue by downgrading the app to version 2.0.7 and attached the debug.txt, hoping it may solve to fix the described issues (since I think I didn’t miss any steps like granting permissions etc - please correct me if I’m wrong)
