After upgrading to 12.4.0 I noticed that the source selector now only shows auto, completely regardless of what combination of settings I use under “Source selector” in the player config. Same behavior in Firefox, Safari and Chrome.
Can you please provide a sample page with an embedded player as well as the UI conf for this particular player?
I’ll be happy to take a look.
So far I’ve nailed it down to using version v2.49 of the mwEmbedLoader2. Reverting it back to 2.46 (Using the UI Confs Managment) brings back the source selector.
I’ve also noted that the players “update them self” when saving changes in the universal studio. Previously I hade to manually click the link for each player to update.
