DM call and server problems

The past few days every time i call someone in DMs while i am on phone it doesn't let me view the call, like i will be reading the msgs and then i want to press the button on the bottom of the screen that says that i am in a call and it wont let me go to the call, it will show slightly of the call which it has the connect to the call button and even tho it actually shows like i am not connected to the call, it shows the hang up button too, my friend can hear me perfectly anf i can hear them too and the screenshare so no problem with those. Plus when that started something else also happen to my servers cause i can't scroll down to check the different voice and text channels, it wont let me scroll down.
