Describe the feature you want

Video not available message is hardcoded to the thumbnail on unavailable/unplayable videos. It would be great if it's changed to a video unavailable text or [better] other text based message that explains why the video is unavailable/playable which follows app language instead of using this [English] thumbnail on every video and on every language.

Additional context

Screenshot:

How will you/everyone benefit from this feature?

People will better understand what's going on because they will see the message in their language also the text on the thumbnail is a bit out of the border (text is too close to the border and not aligned to the center also part of of the last letter E is "cut").

Current dev version show it like this .

So, we just need to crop the current image to not show any text?

Yes. The best solution is to replace it with a vector graphic
