Metamask and Opensea - cannot login

Hello. For some reason, and for the first time, my Metamask wallet extension (which is up to date) isn’t working with OpenSea. I cannot login. I tried on 2 different browsers (Firefox and Edge) and there was no issue - successful login on each.

As such, this appears to be Brave browser specific.

Suggestions? Thoughts?

Thanks in advance.

If it still not possible to use metamask with opensea after selecting ‘none’ in the list, then there might be problem (bug).
