I am trying to download an mp4 file to my iPhone and get the error "Couldn't Save, Sorry, this type of video cannot be saved to this device." I have removed the Dropbox app, restarted my phone and re-downloaded the app. No luck. I have also cleared the cash. Still no luck. Google has been no help. I'm sure I am not the only one with this issue...please help 🙂 Thank you!
