HA companion has stopped using websockets

I had websockets working for notifications by select the “always” for persistent connection, but yesterday it stopped using websockets and went back to FCM which has a massive delay on my phone; please someone help me trouble shoot this, I even re-installed the companion app.

It seems to be working again, not sure what I changed.

just a FYI but you can speed these up without needing the persistent connection enabled.
