First off when I try to join a match will not allow I have turned off my device and tried in many other ways but to no avail.Second of all I would just like to say the snabox I find very difficult ton edit the terrain.
When you say "not allow to join match", how far do you get? A screenshot wold be helpful. If you're on cellular data, try connect with WiFi and see if it helps.
It works now but you might want to check it out it basically does not respond when you try join a match
