steps:

1. build unity-wallet-mobile for android in 2020.3.26f1
2. change moralissetup to use my server uri and app id
3. build and run on device
4. click on "Connect to Wallet"
5. select metamask and press "Connect"
6. Go back to app, see sign message, return to Metamask
7. No popup on metamask asking to sign
   Also tried on Trustwallet, same issue.

There appears to be a crash:

The same settings, using QR code, I was able to see the "Connect" and "Sign" messages in metamask and was able to log in successfully.

I have similar issue. Sing message doesn't pop up every time. My "fix" is to kill metamask completely and usually works
