I'm using what i would say is a top-tier Android phone (Samsung Note 10) with latest software, i take the updates, but after months and months i notice it always loses connection to my tv, i try to reopen the app, and find it's "Finding the last connected Roku device". I cant even back out or do anything, i have to kill the app from the open apps then relaunch the app and go through the process allll over again. It's a BIT annoying to say the least!!! Makes my entertainment center a s***show!
