I've got a theory that they botched the rollout.
The devs have revealed that you have a 10 day window after your subscription runs out to reup and keep your streak. People started complaining about not getting their streak rewards after about 10 days relative to the rollout of the feature, as opposed to 10 days from when any given player had their subscription lapse.
Also yes for those keeping track this means there's now a second form of staggered gold pass where you can both keep your streak, never miss a tour of gold pass rewards, and save a little money.
Though I'm not bothering with the streak rubies/pipe if it turns out to just be a ACA pipe after three months. I want real shit, directed missing tour exclusive shit.
