Video does not play on Safari

Hi - I am working with a Published Evolve SCORM 1.2 module. This is a video based module. I have hosted this output in our proprietary LMS. Unfortunately, videos do not play on Safari on Mac and iOS.
Videos play fine on Chrome on Mac, but not Chrome installed on the iPhone.
Do we need to look at changing some settings on the server? Or should go back to the content developer and ask them to change any publish settings related to the video. Any guidance will be highly appreciated. Thanks in advance.

Hello @VTK - I’m sorry you’re having this issue. Please contact support from inside your Evolve instance giving details of the issue. Support will need any error messages and access to the LMS where the course is being hosted.
