Eufy 2k battery doorbell d/l videos

Recently I can’t download the videos. It stops at 61% and fails to complete the download. I’ve not had any updates for a few months so firmware is current and upto date. My broadband is full fibre 500mb/s so no problem there. The blue light on the chime is lit blue with no errors. Can’t figure this out why it’s just not capable of completing this simple action.
