Do turbo hours still exist?

[Chicago] I’ve driven Lyft for several years off and on, so I know it changes a lot. After taking the summer off, I did one ride last week so that I would be eligible for bonuses this week. The good news is that I got a decent Ride Challenge for this weekend. However, I haven’t seen any Turbo Hours come up for this weekend. As I recall, the weekend were pretty much all Turbo Hours of anywhere from 20-60%, and those boosts were essential to malign the rates worthwhile. Bu so far I haven’t seen anything come up in the schedule.

Have they changed how that works? I’ve seen some posts on here about Turbo Zones showing up on the maps. Are those not scheduled in advance? Any info would be appreciated.
