Just saw the other account invoice paid. Looks like something prevented it from completing. Do you see any errors in the browser development console? Manually adding the other account now.
Discussion
I sent a reply to your other comment with screenshots of dev console. Not sure if I captured the right stuff though.
Testing Alby now. You are using Alby Hub or have Alby connected to a different wallet?
I run my own Alby Hub on a pc. I have Alby browser extension connected to the accounts on the hub.
