We've identified the issue, and are still working on a fix. In the meantime we have identified a workaround that appears to be working on some clients - by navigating directly to https://app.frontapp.com/oauth/google-signin?client_type=universalLink in Safari on iOS and signing you should get redirected to the app in a signed in state
