Meta ai glasses video not playing

I bought myself the meta wayfarers and my gf the meta HTSN. We both have different smartphones, (Samsung and Xiaomi). Both cant play any of the videos shot on the glasses in the app, a workaround of sending ourselves the video through whatsapp works (sometimes). It never has a thumbnail, and it either plays at a low framerate, or it plays once, and then every time after the first a message pops up saying the video is not supported. 

On many forums and discussions I see meta blaming the smartphones because they "dont support the codec" but even VLC for android cant play the video's. And our phones both play the H.265 codec videos from DJI fly perfectly. So its not a codec issue. The only reliable way to play the video's so far has been to upload them to google photos and open then download it to a computer and view it fromm there. What is this issue? I have seen this issue brought up online for 2 years, and still no ACTUAL solution. 

Especially due to whatsapp sometimes playing the video once and then "not supprted" at the second attempt, makes me believe this is a deliberate software restriction. As if meta has a deal with a specific smartphone manufacturer to make the videos only available there....

What can I do to view a video I shot onn my smartphone?
