I updated my Nexus Player to Oreo today. Looks good so far, but noticed i can't sideload apps. I read that Oreo changes the permissions for sideloading, but that the option isn't available the same way its available to phones ( http://www.androidpolice.com/2017/03/21/android-o-feature-spotlight-model-installing-apps-unknown-sources-changed/ ). Anyone figure out how to do it yet?
You have to give the individual app permission to install the unknown sourced app.
