Flashing Video on Brand New Ring Pro Install

Installed the Ring Pro doorbell last month. And every video and live view -I get flashin video.Everything is hooked up correctly with good power and wifi strength is good. I have went thru support and even sent them 5 videos of the issue and was informed that someone will be contacting me with more information. Nothing as of 10 days.Every time I call help- They make me go thru resetting network , reset the device, etc..But nothing gets resolved. Please help. We have had a ring pro for 3 years and last month had to replace the doorbell due to damage from kids. So bought the same ring pro and did the install in 5 mins and now this..I think there is something wrong with the actual device..I can't attach the video. Hopefully I can figure that out and post it soon.HelpS Patel
