Videos Do Not Download or Share - App or PC / Website

I've had two 45 minute plus phone conversations with tech on this, but still no resolution. My app will not download videos at all. It just hangs on "Preparing" indefinitely (we give it up to ten minutes sometimes, and nothing. On the PC, it just hangs with the circle spinning. Was actually able to download two videos in a five minute period the other day, but for weeks before and since, no more will download. Have tried numerous times. Seems that if I could download TWO in that tiny frame of time, but nothing else, the glitch would be on RING's end? When I go to SHARE videos, (from APP) it'll send the link to the video in text or email, but when you try to open it, message says "Video Has Been Deleted by User." Every time. On PC, it simply does the indefinite spinning circle when I click "SHARE." Nothing ever comes up. Again, no resolution after two LONG phone calls to RING tech support. We deleted and re-downloaded the app, did a reboot on the Ring camera set-up as well. And no fix to the issue. Any ideas out here? This issue is basically rendering my monthly subscription useless if I can't share or download videos. Thanks for any suggestions as to what this could be.
