Worth noting, this is in lieu of WoS. The kids used to be on WoS (which was sideloaded anyways) and I always had to log them into the parent profile with my pin each time they wanted to use it so it wasn't ideal. With the latest delighting I just figured it's time to migrate them to a custodial solution anyways.
Mutiny being a pwa solves this since I think they can access a browser on their kids acct... 🤔
