Trouble loading up realms

Ever since the last update, the realm plus option that is supposed to appear in the worlds menu won't load up. 

 

I am afraid that this issue will never be resolved b/c I just bought the "realism craft" texture pack and wanted it to play it on a realm.

 

My friends and I are always having trouble trying to load up a simple realm. Please, I just want to play some minecraft with my friends.
