The latest build (0.2.0) has a log out button next to the account name (Profile > Settings > Account).

On older versions, I think you have to log in to more than one account, or one account twice, before the option to log out appears. If one account is logged in twice, it will fully log out.

If you go to your profile tab, click settings > accounts > edit account, delete your password, and type in anything other than you password. Try to save this, and it will fail to log you in. Now renter your real password and it will save your account info. This acts as a “refresh” for you account token.

It’s a bit cumbersome, but there’s currently no way to manage accounts with only one logged in.

EDIT: I stand corrected, the latest TestFlight has added a logout button to the account settings page.

Oh, so, if you have multiple accounts, then the option to delete them from the app appears.

If you only have one account, you can actually just add it again. It will appear in the list twice, but then you’ll have the delete option. In this case, when you then remove your account, the app will reinitialize, and you’ll have to sign in once more. But then you’ll be all set.

So it is a pretty awkward process honestly if you don’t have an alt account, but I believe the issue is currently being talked about on Github, so it’s likely to be improved at some point
