Embedded video not working in Safari

By default, Safari doesn't accept cookies from cross domains making the use of iFrames with embedded content problematical. This is especially the case for videos, as Google uses the YouTube player and authorization cookies to provide access to this content. Unfortunately, this can only be solved by disabling the 'Prevent cross-site tracking' option on the device that is playing the video. 

Solution

The best solution is to replace the embed video with the Media Player of the Use-your-Drive plugin itself. To do so:

1. Open the Use-your-Drive Shortcode Builder in your page/post
2. Select the 'Video Player' mode
3. Open the 'Folders' tab and navigate to your file.
4. Click on the </> button behind the video file to only use that single file in the Media Player.
   
   

Alternative solution - Disabling the 'Prevent cross-site tracking'

1. In the Safari app  on your Mac, choose Safari > Preferences, then click Privacy
2. Uncheck“Prevent cross-site tracking”.

iOS

1. Open the Settings menu.
2. Scroll down and select the Safari option.
3. Scroll down and tap the button to the right of Prevent Cross-Site Tracking to enable it.
