Leo, I am using O32.0.1948.69, and O32 on my Mobile tablet, on both of those I get this::
An error occurred. Please try again later.
BUT...I just signed in to sync, and now I DO get the normal page. Seems that if you have already reset it (which I always do after I have synced my devices), you will get the error message. I never leave my devices synced, too many problems from the past (jumbled bookmarks, duplicates etc on my Opera for Computer) I will usually sync my Windows laptop first, then sign out, then sync my Mobile. The sign out. Then rest it again
