I have made sure macOS, iOS, and steam link app are all up to date, I can see the iMac in steam link app and when I touch play a new window opens on iMac and it goes to splash screen on iPad. The network tests fine, I have unpaired and re-paired the iMac and iPad. In the stem link app when I stop remote stream on the iMac it shows that on the iPad, so they see and talk to each other. Just the game never shows on the iPad screen , but it plays on the iMac.
What could cause/solve this issue?
