"Unable to connect to world" in Realms. PE
message says to check internet connection and try again.

My internet is fine. I am playing on an iPad. Everything is updated.

I had turned off and turned on. Re-started  the app (several times)

This has been occurring regularly for about 3-4 days.

I played earlier today for a couple hours (after a few attempts with the same "unable to connect..." issue and it started to work finally)

It then stopped working and I am still getting the"Unable to connect to world" in Realms. PE
message says to check internet connection and try again.

I tried from a different device and the same issue was encountered.

I logged out, logged back in, restarted device. Opened and closed the app several times. Still “Unable to connect to world" in Realms. PE

As soon as it shows “Loading Resource packs” I get the “Unable to connect to world. Please check your connection to the internet and try again”

or 

I get a different screen; “failed attempting to join realm. Please try again later.”

I have looked at the other posts and it seems a lot of people have this same issue.

this issue is NOT resolved

Please fix
