It has a LOT of issues still, it has potential, but things like subscriptions rarely actually work for me, and when it does, it takes ages for it to work. Portrait videos don’t work.
I do like how it syncs my watch history, allows me to watch membership content. I wish it allowed me to comment natively as well as like dislikes. However the page button allows you to open the webview for the video giving access to those, not superb, but for sure not bad.
