This is a feature, not a bug. Once you learn the general philosophy, you will be fine. For a 2-lane roundabout: Use right lane if you want to turn right. Use left lane if you want to turn left. Either lane is fine if you want to go straight.
It's like when you approach a traditional 4-way intersection, some of which add a left-turn-only lane and some of which add a right-turn-only lane: once you learn the general philosophy, you will be fine.
PBS Kids has at least two free apps: one video streaming, and one educational games. Both are great.
Sensical [1] is a free streaming service/app that only includes content that meet Common Sense Media criteria. Common Sense Media [2] rates/reviews media for quality and age-appropriateness.
Kanopy [3] is a streaming service/app that is freely available through many libraries. It has a walled-off kids area with movies, shows, and videobooks that are not garbage. I have no concerns letting my kid loose in the kids area to choose among that content.
YouTube Kids [4] is a free streaming service/app that can be terrible or decent. To be decent, you must curate the content yourself (rather than the algorithm) so you have to find and add "channels" or even individual videos, and remove them when they are outgrown. Some channels I found are...
YTK General: PBS Kids (collection of 5 channels), Sesame Studios (collection of 6 channels), Khan Academy Kids, Bluey, Deep Look, PBS Space Time, TheDadLab, Super Sema, Mystery Doug, Brainzy Games, The Kiboomers [for toddlers]
YTK Animals: Nat Geo Kids, The Cincinnati Zoo & Botanical Garden, Animal Wonders Montana, San Diego Zoo, BBC Earth Kids
YTK Drawing: Super Simple Draw, Muffalo Potato, Draw So Cute, Art for Kids Hub, drawstuffrealeasy, Red Ted Art
Enough with the streaming video. For educational but fun apps, I recommend:
PBS Kids Games, as mentioned before.
Khan Academy Kids [5].
Teach Monster: Reading for Fun [6].
NumberBlocks/Alphablocks [7] have freemium game apps (NumberBlocks World, AlphaBlocks World) that combine the show and games. They also have lame free apps (MeetTheNumberBlocks, MeetTheAlphaBlocks) that I wouldn't waste time on.
