Metamask wallet unresponsive

Trying to connect Metamask (9.8.4) in Brave browser (1.27.109) on Mac OS (11.5.1) to Opensea.io. The Sign In button is not responsive. Worked fine a couple days ago.

Also noticed Rarible.com would not load in Brave. Just the spinning icon.

Anyone else have this problem?

There seem to be issues with MetaMask itself.
