I have been playing Roblox for almost 2 years now but I never experienced this kind of bug, I don't know if it's a bug or just my phone but when I join a world and it would be a normal loading screen for a second and it would say "launching experience" like that for so long and when I press the "back" button it would load like you just logged into Roblox again and never go to "home" where you pick worlds it's so annoying I even miss my daily rewards :/
