Realm - Disconnected from Server

I have not been able to get into my realm since downloading the new MCPE update yesterday. I keep getting the alert "disconnected from server." After numerous failed attempts to get in, I deleted the MCPE app from my phone and reinstalled it, but this did not fix the problem. I also tried using different wi-fi networks, to no avail. I can get into Worlds fine, it's just Realms that's not working. I'm not the owner of the Realm, if that helps.
