Cannot update

zmaint, on Sep 27 2020 - 20:08, said: Logged in as normal.  (has been 4 weeks, I have been travelling)  Game launched as normal said I needed to update.   I clicked update.  Gamecenter says cannot update, "we're working on it try again in 299sec.... " then starts a countdown.  Hours later, still says the same message.   Update server broken?  Or is the gamecenter broken......... again/still.
