The only issue I have had with Eero is getting through the sell on the Android app. It always gets hung up on one step or another. Across several phones, several generations of Eero hardware, and using several different modems/routers. A few calls to tech support with no clue. iOS to the rescue. Just today I borrowed another subcontractors phones to finish the setup. So dumb. Once it's set up, the Android app works fine. Go figure.
