Hi,
I’ve just upgraded from ownCloud 9.something to Nextcloud 10.0.5 and from there to Nextcloud 11.0.3. From ownCloud to Nextcloud 10 the Tasks app survived, I enabled it again, everything worked. From NC 10 to 11 it didn’t. The tasks app is gone and it’s not available in the appstore either. Has it been removed for good?
