Using JiveWorld17 Promo Trailer - Courtesy of Dina Vekaria as an example, I am showing the following "Full Screen" option when browsing in Safari:
If your user navigates to that video are they seeing the option present? Or if there is a specific example of a Video here in the Jive Works community where you are seeing the option missing, can you please provide a link to the content?
Lastly, if this is limited to videos/specific video in your private instance I would recommend submitting a case in your customer group ( MyJive Secret Support Group Administration FAQ ) as a next step so that a member of our support team can review through your instance as a next step. When submitting the case if you could include the following information:
- link to an example video where the behavior is seen
- version of Safari being used
it should assist with their investigation.
