there’s on issue that notes how Tasks can crash on interaction, receiving a fix in v1.5 - Tasks fails to get a full access on another Nextcloud instance than e (#6143) · Issues · e / Backlog · GitLab
but I see Info about Samsung Galaxy Tab S2 9.7 Wi-Fi (2016) - gts210vewifi last release was a v0.23-pie?
You could ping [UNOFFICIAL BUILD] Samsung Galaxy Tab S2 9.7 Wi-Fi (2016) (gts210vewifi) if someone is up to make a newer build
or abandon Tasks App of course
