Wizards Unite loses focus on iPhone
I'm using an iPhone 6s Plus and, unlike Pokemon Go, I have the following issue with Wizards Unite:
After a minute or so, the screen will dim and then go off -- essentially the game will lose focus and the phone will default to its power-saving state of turning off the screen. In Pokemon Go, even with the power-saving feature turned on, I never had this issue and in Wizards it is rather frustrating since, even while walking, I can't just keep touching my phone every 30 seconds or so just so it won't shut off.
Is there a setting (either in-game or on the device) that I am missing that would help fix this?
