I have the ring doorbell which has absolutely no issues connecting with the camera preview.
And I have a ring camera, which is near the doorbell, but inside the house, both are connected to the same wifi. The camera struggles to show the preview, we need to keep retrying 6 or 7 times.
Anyone had it? I tried already to reconfigure it, recharge the battery, turn it off and on. Nothing seems to make a difference.
