This is response to an old thread which no solution was ever provided. I have Nvidia Shield, I have old iphone and Ipad, Android TV remote works perfectly once paired no issues. I have a new iphone 11, Android TV remote works, but I have to pair it each time I open the app. if I close the app it needs to be repaired each time i want to connect. This is the only Keyboard app that supports Paste function. so the Nvidia shield remote is worthless with out the paste function.

So has anyone else had this constant issue of Pairing each time you open Android TV app and found some resolution. Since it works on all my devices except the iphone 11 I presume its something unique to those phones and how they store the wifi pairing information
