Pain to switch email address

I am forced to switch email address for my Floodlight Camera 2k. The only way to do this is to delete the device, after it was setup, mounted, and running. Then delete the account and create a new one. Now I have to add the device that is already mounted and impossible to scan the QR code on the device and have thrown up the documentation box. I was finally able to get the S/N and manually enter it in. Now it will not connect to the cell phone. I have turned off the 5G network on my router and still will not connect. Dead in the water now.

Got it running again by uninstalling the floodlight camera and app. Turn off 5G wifi and still had issues connecting while inside my house. I suspect it was other bluetooth devices near where I was trying to connect. Moved outside and was able to connect. Still a pain just to change my email address.
