Issue with phone as device

Very new to hubitat after just migrating over from wink.

I had a very brief power outage last night, which included my hub (ordering a UPS). I ended up having to delete and reinstall the app and everything is working as usual, other than notifications to my phone. For some reason it is not recognizing my phone as the same device previously linked to the hub and I get an error message when clicking on the notifications section of the app. If I check the events for my phone under the device list it shows all notifications being sent, but I am not receiving them.

I tried rebooting hub, deleting a recreating a rule with no change. I also tried logging out of the app and logging back in, and again choosing my phone as the device previously added. Now the error message tells me the device is not connected to my email address.

What should I do to get the hub recognizing my actual phone as the correct device?

Thanks in advance!
