I have two Ultra devices, and I would like to control them from mobile devices. I have installed the app on two Android devices and two iPhones. They all work and can find the devices EXCEPT for my wife's iPhone 15.
It's a relatively new phone. The Roku app was just installed fresh. I have checked to make sure the app is signed into the correct account and is on the same wifi as all of the other devices. On this iPhone, I can go into account information and see what devices are associated with the account, and they're both listed.
But when I try to use the remote feature in the app, it is unable to find any Roku devices on the network.
What else can I check to see why this one iPhone can't find any of the devices?
