We do plan on updating next week to the new code.
I just noticed today that the CPPM entry does get pushed to the master controller almost immediately. I must've missed that before -- I don't usually look at the master since no APs terminate on it.
It's the replication to the local controllers that is taking 24 hours. Everything else we do, such as updating configs on the master through the gui, will replicate immediately. It's just the CPPM database that takes so long.
