Idk what is wrong with it

I switched to an iPhone from a Samsung S7 and now everything is wrong with google play music the music will pause and it doesnt have the same features it has on the samasung I think google play should fix google play music for the iPhone bc people are still paying yall money for your music app so the least yall can do is give us good quality just as if this was a Samsung
