App doesn’t even open – MiniYT for YouTube Review

I tried this app on my Apple Watch series 3 just to see if maybe I would be lucky to even get the app to work. But I can’t even search for a YouTube video. When ever I click search or click trending the app just crashes. And no, it is not my watch. I tried restarting, I even reinstalled the app. It is just this app. If you can please fix this, I will bring up the rating. If not. Then the review will stay. UPDATE: Thank you for the fast response. If I would have known the app currently was not supported on the series 3 I wouldn’t have bought it with my money... All I saw was watch OS 7.0 (I had watch OS 7.3) or later and I purchased the app... However thank you for the fast response and I will be following discord for updates.
