Home Security Camera Issues - Help

[bigdog]

I'm having issues with my home security cameras.
Cameras are made by Reolink.

I've had these cameras for a couple years and work flawlessly managing with my mobile phone, however, issues began when I upgraded my phone to a new T-Mobile Revvl 6 Pro, which runs at 5G.

I think the issue is that the cameras are not adaptable to the 5G technology.
Old phone was T-Mobile but ran 4G.

Do any Forum member have Reolink cameras and having similar issues ?
