Hello Mojang! I play Minecraft PE and I have a problem. I cantc connect to WiFi. I can't play with my friends and I can't play in servers, because of this problem. I tried restarting my phone but nothing happened. I even tried turning off WiFi. I'm scared to uninstall Minecraft because I have had trouble in the past with losing my progress. I don't know what to do. Is it a bug? Can You please help me?

Sincerely, Paula
