Odd on part of the thread it says 2020 but then when I click the download link, it then says it was updated recently. I'd use it but I don't think Sims 4 auto generates teens, all I ever see in the towns and vacation spots are children, young adults, adults, and seniors, no toddlers or teens, and all of my Sims go to planned parenthood if they get pregnant...
The unlocker doesn't spawn teens or Sims in general. All it does is unlock WW features to use with teens because Turbo was forced to remove it from WW due to guideline issues with Patreon.
If you have issues with teens spawning, maybe you have another mod that controls how townies are spawned in the game, for example Sim Spawn Overhaul by Lotharihoe or Townie Overhaul by Bienchen. These can limit the amount of townies and the kind of Sims that are spawned. I'm not sure but it wouldn't surprise me if you can also control this to a certain degree with MCCC.
As for teens using WW features, you need the unlocker or the setting to enable romance with teens in WW won't show at all. If you have issues with teen pregnancies and use MCCC, then you need to also enable teens at an age group to get pregnant. This is a setting in MCCC.
I'm using both mentioned above mods to control Sim spawns along with MCCC, WW and the unlocker. I'm using Sim families I've created myself and usually delete existing families. To get to the point, when my Sim families have babies and they grow up to be teens, WW and the unlocker work as intended and it's completely possible to have teen pregnancies just by using the WW features.
