Issue description:

User has a Canvas app - with gallery, and inside this galley there is a video control. The gallery is loading videos from SharePoint Online Library.

It doesn't work in 3 cases:

1. If the user never opened the SharePoint library before, and starts the app, then videos don't load.
2. On Mobile App (Android) also doesn't load.
3. On In Private mode Edge browser, videos also don't load.

It only works in 1 case:

• On normal browser mode, but before opening the app I have to open the library in SharePoint Online first.

Also showing JavaScript error in console:

The resource https://content.powerapps.com/resource/webplayer/hashedresources/7it1ki1u1rt5f/js/player-loader.js was preloaded using link preload but not used within a few seconds from the window's load event. Please make sure it has an appropriate `as` value and it is preloaded intentionally.
