I have played multiplayer pocket edition minecraft with family for two years and have had no issues. But since 1.13 we haven't been able to connect. It shows beside the friends button that someone is online, but it doesn't actually gives us the option to connect to the game. I have four devices and have tried to use games from all of them, and we are all connected to the internet so there shouldn't be a problem. I hope you can fix this bug soon so we can all play together again soon.
