I have not heard anything back from 'Tech'. They said the case# for the issue is #76487 and that they are aware and working on it.
I'm not confident it will be fixed. Otherwise, why wouldn't have Bookmaker been fixed yet? It has been months since Bookmaker data stopped loading regularly into Game Center. And when Bookmaker data has appeared, it is often hours or even days old.
Other places I have found betting splits do not include nearly as many contributing books as Pregame once did. VSIN seems to include only MGM & William Hill, and it does not update at all; one screenshot per day. I hope Pregame gets it back to working the way it used to; I find it to be an invaluable tool. But it's also free, so it is tough to complain.
