That is entirely possible. I use Alby for both signer extension and zapping, so I haven't had any similar issue.

OK... after a lot of trial and error I seem to have come right. Definitely was a problem of having both nos2x and ably on at the same time. In some way it wasn't compatible, but I can't quite say how. Any case, crossing fingers that it just keeps going.
Definitely working! Glad I could help!
