MTS Blocking came back today. On this computer, it won't connect, and I get this message:

"iglbakfobmoijpbigmlfklckogbefnlf is blocked
Requests to the server have been blocked by an extension.
ERR_BLOCKED_BY_CLIENT"

I have 3 extensions, the same on all 3 machines, and all are running Chrome 90.0.4430:
Bitwarden PW Manager
Tampermonkey
and MTS

On my computer #2, when I click on the bookmark for either of those extensions, I get the login page for Turkerview.

And MTS on the 3rd machine is behaving normally, just to make this more puzzling.
Which is also why I have 3 computers.
