I have developed an iOS app (Xcode/Swift) that gets webviews from a Wordpress page. These Wordpress pages has embedded Vimeo videoes, which are hidden from Vimeo search and can only be seen and embedded on my domain.
I have a Wordpress plugin for embedding the Vimeo videos. Lately, in the app (not at the webpage/desktop view where the content also can be viewed), instead of showing the video I get the message “Sorry, because of its privacy settings, this video cannot be played here”. When I go back to the menu, and then back to the video page (web view) a few seconds later, the video is shown and everything's working.
Is it something wrong with the plugin I use?(https://wordpress.org/plugins/advanced-responsive-video-embedder/) Or maybe a cache delay?
Or, can it have something to do with iOS9? I have the latest 9.3.1 installed.
