Kabam I submitted a ticket a while back about this issue, and it feels like it was just ignored. It is a very annoying bug. Basically if I accidentally swipe the control center on my iPhone, the resume button never shows up and there is nothing I can do other than closing the game. Please fix this issue, it is very annoying, speciall when you are on AQ or War, because I loose half health 🤷🏻♂️
