The issue
Whenever I try to join any servers in Minecraft pocket edition, the “Connecting to external server” loading menu appears but after some seconds, the entire Minecraft app is closed automatically. Thereafter when I re-open it, it starts from the scratch.
A twist
With using Wi-Fi (not shared WiFi like mobile hotspot from another phone's Sim card internet and doesn’t matter if vpn on or off), the game never crashes while joining both already running servers and already stopped servers (I am not taking about the online-mode=true or false things)
And with using mobile data (no matter vpn on or off), the game only crashes while joining already stopped servers, on the other hand joining already running servers works very well.
I guess if the bug fixer team focus on this twist, the bug can be solved with more accuracy.
Steps to reproduce
Open the Minecraft Pocket Edition game
Wait until it loads its contents in the main menu screen
Tap “Play”
Go to “Servers” menu
Select any external server(s) and tap “Play”
Wait for around 10 seconds and you will see the game entirely closed itself automatically.
