AA also canceled the Friday (Dec 13th) return from SXM to CLT. I guess I'm "special" because we got TWO e-mail notifications - I woke up to one yesterday morning and they sent another (identical) one overnight last night. They also changed our routing down on Nov 30th as well.

Our friends who are traveling with us on the same flight did not receive any notification of the change. We were originally on a red-eye from PHX to CLT, now we leave much earlier and have to overnight in CLT on the way down and MIA on the way back. Oh well, at least we still have a flight to our favourite holiday destination!

I agree that this all has to do with the 737-MAX taking longer to resolve than originally anticipated. It doesn't really matter if your flight is on one of those planes or not. The airlines are short of planes and will have to cancel flights somewhere.
