This screen appears while your wallet is being created or your sign-in is being finished. On some devices it can hang there, mostly on Android.
Do not keep re-creating wallets. Repeating the sign-up in a loop does not clear the hang, and every attempt that does go through leaves you with another new, empty wallet to sort out later.
What to try:
- Close the app and try again later — the hang is often temporary.
- Update Google Play Services and Android System WebView from the Play Store, then retry.
- Try the other sign-in provider (Apple instead of Google, or the reverse) if that provider is available to you.
If it still hangs after all three, contact support with your phone model, OS version, app version, and the exact text shown on the screen where it stops.
