Roblox app error.

Can anyone help please? Here is the deal. I was trying to join a game through private server link and its just sends me in to main page of roblox client app. I tried again while it was open and it still didnt let me joing a game. And thats not all. Then i try to join a game through browser it just sents me main page in app also and not game itself, basicly focing me to use app. I tried deleting roblox and downloading it back, didnt work. Also deleted all extensions on browser and all the same. Any way i can fix it?
