Cam Plus Video jerky and only 2 secs long

I have 5 Wyze Cam v3 in various locations, I have 4 Cam Plus and 1 cam plus lite services, around a month ago the playback on the 4 cam plus cameras became very jerky and only 2 seconds long but the one on cam plus lite works fine. Since then I have done resets and restarts to no avail so now I have put all the cameras on cam plus lite and they all work fine, but if I put them back on cam plus the problem reoccurs, any one got any ideas?
