Realms won't load

After this update said I had to be on wifi to access my realm and it won't load even on wifi not happy I want to be able to play on either wifi or cellular which I was able to do before the update tried to Uninstall and reinstall it but still didn't work I normally play on my phone pocket edition only but because I can't get in none of my friends can now get on and yes my realm is up to date paid for
