If when you attempt to open the TrustVault MetaMask fork and after entering your password the MetaMask shows a spinner like below:
This may be because you have recently logged out of your TrustVault iOS app. This removes all login tokens globally which, unfortunately, the older TrustVault MetaMask extension could not handle.
To fix, either:
Upgrade to TrustVault MetaMask 1.3.3
Disabled the extension from Chrome / Brave and then re-enable
NOTE: If you have non-trustvault wallets please ensure you have backed up your seed phrase before disabling in case of any issues.
Once, re-enabled you will need to re-connect with the TrustVault using the instructions here.
