Completely Broken

When starting the app for the first time you are forced to go through an unskippable wizard to create or login to an account. Go through the whole 2FA rigamarole and you must then make a new starter. And again, no way to skip.

Step 1 is name your starter. No matter what happens there is a server error and you are stuck on that page. No skip. No back. Nothing.

The only option is to force quit. Which starts you back at step #1 again. I’ve uninstalled the app, rebooted, reinstalled multiple times. On WiFi or cellular. It doesn’t matter.

I’ve seen zero evidence that this even is an app. Just a few stock photos and a simple wizard that collects email addresses and verifies they work. This kickstarter I backed feels sketchier by the minute.
