Here's my scenario. I just don't wanna waste my money I spent on 3 month XBL codes.
Game Pass Ultimate: active until 10/4
Recurring Billing: currently off (it appears if I re-activate, they'll charge for a minimum of 1 month for $15 starting on 10/5, even if I cancel the recurring billing before 10/4)
Purchased: 4 - 3 month XBL Gold codes, which, to my understanding would convert to 50 days of Ultimate for every 90 days of Gold (i.e., 365 days = 202 days of Ultimate)
The question is, does recurring billing need to be turned back on in order for the XBL Gold to get converted or can I simply add these codes and they'll get stacked on and converted (or allow it to be converted)? Thanks in advance.
update -- I think I found the best guide:
