I've been using Jerboa for Lemmy for my Beehaw account since the Migration. At first it worked fine. Then I started getting an error message about the version of Lemmy being used on the instance. But for the last couple of days it has been crashing immediately on opening:
The most recent jerboa version doesn't work with lemmy version 17 anymore (which beehaw is on). I had the error and crash happen too. You could download a previous version off their github and it should work with v17 instances (but probably not v18).
But I'd recommend liftoff, it was recently added to the play store and it's actively being worked on! It's the app I use and I've been enjoying it so far.
