IMy cameras have stopped recording videos

My eufy2 cameras recorded ok until a few days ago but suddenly they have stopped recording any videos. I get notified of motion detection but no videos. I can watch live stream. and manually record and save live. I have uninstalled each camera and readded them but that didn’t help. I haven’t changed any settings. I also keep getting this msg "unable to play. The file has been deleted due to over writing or manually deleting. Retry. " Well I haven’t deleted anything as there wasn’t anything there in events to delete. Would a latest update have caused these problems. I have emailed support but no response. Can someone please help.
