What happened to this app????!!!!

This app was my favorite and my main youtube player but with the latest update it only crashes and I cant even open it anymore on iphone 6.
Please fix it asap or I will need to delete it forever. Its been almost two weeks since this unfortunate update but still no fixes yet. If i was a developer of this app, I would do all in my power to do something about before its too late.
This is quite upsetting !!!
