@egil @lppedd There are no plans to work on Android/iOS in the near and pretty far term. It's one of the epics on the roadmap but very far along, https://gitlab.com/groups/gitlab-org/gitter/-/epics/6
There is even a slight itch to deprecate them because of those bugs you mention, gitlab-org/gitter/webapp#2281. If some of the bigger bugs are fixed that you mentioned, then we can leave them alone. Merge requests welcome!
The notification issue is probably this, gitlab-org/gitter/gitter-android-app#121
