Ring 1st Gen recording blank video

Hi all,My 1st gen doorbell is going a bit crazy. Firstly it very intermittently works. Most of the time when people press it nothing happens. There has been no change it my set up with WiFi or anything.Now, when it detects motion all I see on the App is 100% black footage. Not dark, not a lack of light, but totally, no data, blank. But when it's recording time lapse footage it's absolutley fine.I fear it may be past it and needs replacing, I've reset, recharged and done everything. Do Ring do repairs?
