Hi All Just wondering how does Growth Book manage to assign which device has got which variation on an experiment • when the variation would be assigned? when the app launch and growthbook sdk is initiated? or when the method "gb.feature("xxx").on" is calling? • once variation has been assigned, how long that variation maintain its value on devices/users until reset? is it gonna be forever? or there is configuration for ttl on this? • if variation once assigned then it cannot be changed, how will we reset it? will uninstall the app do ? perhaps reset cache data (on android) also? thank you in advance for helping me clarify these questions

GrowthBook is pretty flexible on when assignment happens. Typically its on SDK side, using our deterministic hashing method: https://docs.growthbook.io/faq

by reseeding assignment, that would effect all users, right? but I am talking about scenario that user got an assignment 2 months ago and they probably forget what they saw on previous login. I want the them to got new assignment base on current allocation between A/B variants. is that possible?
