I rang Disney IT today about a problem I was having booking my FP+ options. I was told that November is definitely still in testing, and not all resorts were part of the current testing phase.
Apparently, the system will only accept up to 14 day reservations for FP+, after that you need to use paper FP. He also said that some resorts will be part of the testing in October, but then will be removed again for November.
I have Magic Bands for 2 of my 4 reservations, All Star Movies and Wilderness Lodge Villas. I haven't been offered them for my Animal Kingdom Villas or Old Key West stays. Apparently OKW will be part of the testing for some dates in October, but not November.
