I have just bought a new Apple TV, didn't check how to copy all the apps over to new Apple TV, just went ahead and replaced it so have not got all the apps I had before. Have just read that I should have synced the Home Screen, is there a work around I can now carry on to locate and install those app.

If you have more than one Apple TV
associated with the same Apple ID, you can keep the same appearance and
apps for each device. This makes it seamless to switch between an Apple TV in the bedroom and one in the living room, for example.
