History Videos

Just installed a Ring Pro 2 doorbell and it all works fine expect one thing. We have the app on 2 phones. On my husbands Samsung, when you select the history tab, and click on an event, the videos refuse to play. An error message appears stating: "Hmm, something when wrong. There was an error while trying to play the video". I don't believe the issue is signal as there is a good wifi connection and the history tab videos play fine on my phone (nokia) which is sat right next to my husbands phone and within 2 metres of the router. Also, the videos will play if I click on the camera and select from the timeline, its just via the history tab there is a problem. I've uninstalled and reinstalled the app. I've checked that all permissions are granted including camera and media. Can anyone suggest any reasons why history event videos will not play?
