Before You Download
Two checks prevent nearly every failed setup. First, the Wi-Fi check: the phone and the TV must be on the same Wi-Fi network. A phone on mobile data or a guest network will not find the TV, however good the app is. Second, the TV check: the TV must run Android TV or Google TV. Samsung, LG, and Roku sets do not run Android, so the app cannot work on them.
Third, the phone check: the phone needs Android 9 or newer and a screen lock. If those three checks pass, this page is the next stop.
Installing After the Download
Install the app on your Android phone from the download page. Open it on the phone and follow the steps it shows: put the TV on the same Wi-Fi, switch on network debugging in the TV settings where the app points you, and approve the trust prompt on the TV with the remote, ticking Always allow.
Then read the analyse plan in full. Check what goes off and what stays, confirm the apps you use every day are on the keeps side, and only then tap Make it clean. After the clean, try your main apps and, if anything is missing, put it back from inside the app.
