I Play Minecraft what’s my niece. And she has an iPad and I have an iPad. Both the same so iOS.  We can not connect or it say time ran out.  Everything I looked up is check your multiplayer setting.  When I do it’s in gray so I can’t even check it.  

how do I get this fix? We like playing on Minecraft, but if we can’t join it’s no fun.  
what else can I try?  No I don’t want to install the app.  I have world 🌎 on mine I would like to keep. Same with her.  Please help. Thank you. Rebecca Preston
