For your login issue:
Is possible that Phantom wallet installed on the same browser creates problems?
Yes, we do not suggest Phantom wallet in the same browser as MM or Coinbase Wallet. They all compete with eachother and cause bugs. Login will most likely work just fine if you have just one enabled.
For supported combos see: Manifold Studio wont prompt Metamask Desktop - #5 by brooksgallery
Confirmed Working Configurations
- Metamask alone
- Metamask with WalletGuard or Revoke.cash
- Metamask and Coinbase
- Metamask and Coinbase with WalletGuard or Revoke.cash
- Mobile Metamask (with WalletConnect)
- Phantom on its own
- Phantom with Metamask (though we do not suggest)
Confirmed the following have issues:
- Phantom and Coinbase together are really buggy, Phantom seems to think Metamask is installed when it isn’t.
- 3+ wallets installed at once creates all sorts of weird bugs
- we’ve yet to add Rainbow wallet support yet
