Why won't Facebook messenger videos save?

[AC Question]

why won't Facebook messenger videos "save"

I bought a tablet, tab A, for my wife to view videos sent via messenger from Australia. She had a kindle fire and had no problems. The Tab A will play on messenger app, but will not save to anywhere. It looks like it has but when you go to play it, it runs for a couple of seconds and then says " can't play video" desperate for suggestions please

Welcome to Android Central! Do you know if the videos are saving to Internal Storage or the microSD card? If the latter, then it might be a problem with the card. See if you can change the default save location to Internal Storage, or just unmount the card (in Settings>Storage) and then remove it, then try saving the video again.
