Man, so sorry to hear this. Frustrating I know.
As a general PSA: having multiple wallets installed can cause lots of issues, so I highly suggest keeping each wallet extension in its own Arc/Chrome profile. They all seem to be fighting each other over their own standards, which has the trickle down effect of making things like loggging in to Manifold Studio buggy at random times when one wallet provider pushes updates that breaks the handshake they have with another wallet provider. I’ve been burned by this so many times on every dApp that I just presume if I have two wallet extensions installed I will have issues.
Going to dive in today and see what I can do to support Phantom correctly when MM is also installed! I know we have CB + MM working nicely, and Revoke and WalletGuard shouldn’t arise any issues. Thank you all so much for the detailed reproduction steps and patience, very very helpful.
TLDR; In the meantime when ya run into issues like these and have multiple wallets installed, give it a shot using a chrome profile with just that one wallet installed and you’ll definitely have a smoother experience.
