Hey! It seems like you might be on an old version. The latest general version should be v0.2.1+13. You can double check the version you're currently using by going to the bottom of the Settings page
Yeah, I uninstalled and reinstalled on play store (f-droid and neo store refused to install, the apk from releases crashed when I tried to log in) and now it works
There are only swipe gestures on android, there's no three dot menu (or even upvote buttons) :(
EDIT: It worked by reinstalling from the play store and long pressing. Though on the latest APK from github the app crashed when I tried to log in, and F-droid failed to install it (from two clients)
