Whenever I try downloading a world from MCPE addons, I get kicked off.

So, this is what's happening. After I got The Phantom update, I tried downloading a world from MCPE addons. It automatically kicked me off when I tried to get on. I tried multiple times and even shut down my iPad twice. I tried other worlds but the did the same. I also tried it with addons but it's still kicked me out. This is also happed to my friend when I was at her house.
