Blurry video for the first 4 seconds

Hi everyone, I have several Ring cameras set up around my house, and I have noticed that for every recorded events, the first 4 seconds are always very blurry, which is not good as I am unable to identify people's faces or see other details.I am using both Stick Up and Stick Up Pro cameras, on wifi.I moved the cameras right next to the router to ensure the best Wifi connection, but the blurry videos are still happening at the begining of every recordings.I tried to desactivate HDR and/or Night Colour, but it doesnt help.It sounds like it could be a Ring bug.Anyone else has the same issue or managed to fix it ? if possible at all ?
