Embed dropbox video code. Video not playing on iPhone (Safari, Chrome)

Hi, Community!
I have the following problem:

Current plan: Studio

I embed the code in my project to play the dropbox video:

  1. Everything works fine on desktop
  2. On mobile devices on Android, it is also ok
  3. On the iPhone, it does not play (chrome / safari)

Has anyone been in a similar situation?
Thanks in advance :pray:
