my .mp4 file is stored on drop box and the audio playback is distorted when i playback on iphone. no problem when playback on computer or if the file is downloaded to my iphone and played back locally

Hi edmondcr - thanks for your cooperation so far.

I've just sent you an email to look further into this issue, so please have a look at your inbox and we'll take it from there. 

Hi edmondcr, can I send you an email, in order for us to have a closer look?

I tried. Still have the same issue.

Hey edmondcr, have you tried uninstalling the app, restarting the device and reinstalling it, to see if it helps?

Thanks for giving that a go for me edmondcr 

May I ask if this happens on a web browser as well or if it's just affecting the mobile app?

Also, could you clarify your device's exact OS version and the version of the Dropbox mobile app installed there as well?

Are only mp4 files affected by this or is this happening with other types of files as well? How large are the files in question by the way?
