Product Change From United Explorer To Quest

Did a product change to Quest from Explorer a few days ago with my original open date in Feb 2024. My one-time United passes were removed and I got $200 deposited in TravelBank. My AF will not be billed until Mar 26. Did not get my 10k miles for adding an authorized user.

Does anyone know how the 10k mile discount works? Like if I get a discount between now and Feb 2026 and after my anniversary date which I was told 3/1/2026, will I get another discount?

Thanks in advance!
