Stick up cam pro wired

Hello, I have a stick up cam pro wired version and I found that it records only for the allotted time in the video settings and then stops recording regarding of ongoing activation. It then goes to sleep and doesn’t reactivate for a couple of minutes. I spent over an hour with Ring Support sending them videos et cetera and they eventually sent me out a new camera. Unfortunately the new camera does exactly the same I have full fibre WiFi with an R/S of 55 Any ideas? Thanks, Simon.
