Ring Doorbell Pro Image issues

Every so often, Ring Doorbell Pro "detects" motion & sends several motion alerts in a very short period of time (usually 1 ever 30sec-1min lasting about 7-10min) & then will either have a completely blacked out live view (or recorded motion) or the image will be grainy and cut up with lines to where it is incomprehensible.Have tried both a soft & hard reset, still happens.First time it happened, was back to normal in a couple days. Last 2 times it happened, we were without the ability to view for over a week.Anyone able to help with this? Or does it sound like defective hardware
