How long does a Feature Flag take to roll-out?

I have a feature flag called "location-finder-promo" which I published about 30 minutes ago. It seems like the properties and "enabled" states are not coming through, even though this is rolled out to 100% of users. I'm wondering if there is some sort of cache clearing to do, or roll-out time that I have to wait for.

Also... I created a feature flag a few days ago, which I am able to load in my front-end javascript, but then I archived it... but I still see it in my front-end despite refreshing and cache clearing.... I'm wondering if this is the same issue, i.e., some sort of Braze cache that needs to clear, or very long roll-out time.
