This is not possible and Ring is doing nothing about it.
You better sent it back and buy another brand that cares more about his custumers.
Ring is too expensive for a bad service....
Why is this absolutely essential function still not working?
I have been a RING customer for many, many years, I am even a "deep beta tester", and the absence of this once very common feature is completely unacceptable. I have pointed this out in many beta tests, and many times I have been assured of a remedy.
Unfortunately, it is still not functional to this day!
And of course, in the RING app, I have turned off notifications on all home wall-mounted tablets to show instant live video in full screen, not a banner to run it manually !!
