When switching accounts, I'm now seeing crashes

I'm able to reproduce this on my end as well. I'll see if I can't release a hotfix for this tonight when I get home. Thanks for letting me know about this.

v0.4.5.10 had a lot of major changes behind the scenes, and a few issues slipped through that I didn't catch in my tests.

I am also seeing this in the latest TestFlight version. Shared the crash report a few times.

If you need to switch, you can set the default account in the settings to your other account and reload the app to get in.

I just released an update to address this issue, thanks for letting me know about this!
