Can't play video after sending it
After I export a video (Format: H.264 any preset) it plays on my laptop but if I try to send it (either using gmail, dropbox, wetransfer or even whatsapp) it doesn't play anymore. It doesn't work for the person I sent it to or for me if I try to open the file from my phone. It started happening a few weeks ago and then it resolved itself on its own, but now it's happening again.
Anyone know what could ne causing the problem? I didn't change any setting manually in this time.
