No additional errors when clicking the checkbox

Hm strange, i can reproduce this on my production instance but not on my development setup with 1.0.3 :/

[reox]

Has you upgraded the production instance while the dev system is fresh? Maybe it is an issue which only appears if the instance was upgraded before...

[SebastianHeitz]

I was about to report exactly the same error. However, I can add as additional information that the checkboxes remain filled in when using the Deck Android app. Maybe this information will help to solve the problem.

Android 10
Deck app version: 1.4.4
Deck version: 1.0.3
NC version: 18.0.4

An additional note:
When changing the checkboxes in the "Edit description" mode it is saved correctly.
Only in the "View Description" mode the problem arises.

I now this issue is closed but i am having exactly the same problem.
NextCloud 27.1.3 on Docker

The release is still pending, likely next week I'll push a new patch release
