Samsung S9+ loss of closing app feature after upgrade from 2.0-s to 2.1-s

The issue mentioned (and from the reported experience of other “new users”) seems quite non specific.

hmmm … partly due to devs working remotely we are asked to file issues on Issues · e / Backlog · GitLab.

But hopefully your post Feedback for v2.1 - #173 by voidout may find its way back to devs.
