"Yeah, this kind of issue has been around for a while — a lot of these Android TV remote apps either lose support or just randomly stop connecting, especially when services change or apps get abandoned. I’ve run into the same thing where one day everything works, and the next it’s just “can’t connect” for no clear reason. Honestly, switching apps usually helps more than trying to fix the old one. I recently tried a few newer remote apps and noticed they’re way more stable and less bloated. One I stumbled on (https://apps.apple.com/us/app/remote-control-smart-tv/id6758938656 )was surprisingly smooth in terms of connection and basic controls — nothing fancy, but it just works, which is kind of the main thing here."
