AutoRemote Two phones with same URL

I made the mistake of restoring a backup on my old Samsung Galaxy S5 and my new Nokia 7Plus. Now both phones. I tried deleting both phones from my list, then I tried deleting App Data (as described in FAQ's), but that option was only available on my Nokia, not the Samsung. Then I removed AutoRemote from both phones and reinstalled but both phones still have the same URL and I can't add either phone to my list of shared phones. Is there any way I can just remove all trace of AutoRemote from both phones and reinstall so they each have their unique identity?

 

So does that mean I can't use AutoRemote to communicate between the two phones?

 

That seems strange. What makes it more frustrating is that if I look at registered devices on my Nokia, my Nokia is in the list. But if I look at the connected devices on the Samsung, the Nokia is NOT listed and I can't add it. I had intended using the Samsung from home to send messages to the Nokia while I am out and about, but because of this anomaly, I can't do it.

Is a factory reset a Very likely fix, or just a Maybe? Not looking for a guarantee, but doing a reset and reloading everything on the phone will be a pain.
