The only upgrade I ever got was before I was
DVC. I was on my honeymoon, at the contemporary and they had booked me partial garden wing and then had me moving to another room in the main resort in the middle of the stay. The CM was confused (since I had purchased the entire thing at once). and tried to find me a room I could stay in the entire time - they managed to find a 1BR in BLT. That's the trip I purchased DVC (I liked it so much I bought).
The only thing I can sat about the FB group (I think it's the same one I am on).
1. Remember that even the number of people on there are still a small number of people compared to the number of DVC guests staying. It's really, not that big a percentage.
2. It's a pandemic. Disney is doing a lot of shuffling to either Distance rooms, give them time to clean rooms, and deal with maintenance issues. It's stabilizing already (i.e. you may have already missed the horse) and will continue to do so.
