Reproduction Steps:
- Use any other mobile app that is no the official Roblox mobile app.
- Open up the official Roblox mobile app and join any game.
Issue:
Whenever I use another mobile app that is not Roblox, and then I open up the Roblox mobile app and join any game, the in-game sound becomes silent, music and sound effects included. I have found to fix this I have to restart the Roblox mobile app.
