Issues with push notifications on Android 11

I am having issues with push notifications on Android 11 - the phone is LG V60 ThinQ 5G. Specifically no push notifications are coming in at all. Just upgraded my phone and prior to this I had an Android 7 and everything worked fine.

I uninstalled and cleared data on the old phone and the new one as well. Fully logged out then uninstalled on the old phone with the data/cache cleared.

Followed the procedure outlined at Why am I not getting notifications on my phone? in regards to the Android reinstall.

Would anyone be able to suggest other fixes? Thank you for the help in advance.
