Cannot connect to itunes store error

On my ipad 4 the apple id is logging in but the itunes store is not opening now, it used to open just fine 3 days back with my brother's id and now since i switched his id with mine it is not opening. The find my tab is also off, the icloud is also not opening and it is giving the same error.

The apple id is logging in but the itunes store is note opening neither do the icloud or imail work on new ipad 4, I tired every trick there is on youtube from turning on and off wifi. airplane mode, date and time, region selection but everytime it doesnot connect to itunes

I am so ****** off at this apple product, my android is way better and user friendly. I feel like throwing it away
