Describe the bug
After upgrading to Deck 1.4.4 I can no longer access the automatically created calendars/tasks via CalDAV. I always get a 404 error. Access via the Nextcloud Calendar/Tasks web apps still works.

To Reproduce
Steps to reproduce the behavior:

1. Upgrade to Deck 1.4.4
2. Try to sync Deck tasks with TbSync plugin (Thunderbird) or DAVx5 (Android)
3. PROPFIND returns 404 on each access attempt.

Expected behavior
PROPFIND should return 207 and synchronisation should continue.

Client details:

• OS: Linux/Android
• TbSync 1.24 / DAVx5 3.4-ose
• Device: PC, Sony Xperia XA2

This is an actual error from the nginx server access logs:
Client-IPv6 - xxxxx [14/Sep/2021:13:27:35 +0200] "PROPFIND /remote.php/dav/calendars/xxxxx/app-generated--deck--board-2/ HTTP/1.1" 404 11 "-" "DAVx5/3.4-gplay (2021/08/31; dav4jvm; okhttp/4.9.1) Android/8.1.0"

[privong]

For me, this error persists in version 1.4.5 of Deck.

[noci2012]

This seems to be a problem between CalDAV & Deck.

[birefringence]

I upgraded to NC 22 and it is working again.

[Thom1b]

I upgraded to NC 22 and it is working again.

It's still not working with NC 21.0.5 and Deck 1.4.5.

[privong]

I upgraded to NC 22 and it is working again.

I report the same; I no longer receive errors about sync'ing via CalDav. There was a message when upgrading to Nextcloud 22.2.0 that deck would be disabled, but it was still enabled when I finished upgrading.
