Yeah it’s v.redd.it links that won’t play in-app. If you view it externally it should work.

This has been raised as an issue and hopefully will be picked up.

Or have you found something else? Some more details would be nice

If you check the domain I believe you’ll find it’s mostly v.reddit links. There’s one power poster throwing quite a lot of them out at the minute, so we might need an update from Lawrence.
