Can you please make sure this is still an issue in an unmodified version of the game? Mojang does not usually accept reports for modded versions.
The Mojang team cannot help you with this. Contact the server staff please.
Which server?
I believe that your troubles are caused by the fact that your app version is very old. Try updating your app.
I'm pretty sure that this is feedback and not a bug, in which case it should go on feedback.minecraft.net.
