Why is not working on my phone🤨

So it works fine on my laptop but whenever I want to use it on my phone it doesn’t work. I try and search videos up and even filter them it still doesn’t come up. But I do the same thing on my laptop and it works fine?.

Video graphic crash on iPhone 6

In every videos I’ve watched, they have the same problem. Video graphic crash, the video graphic turns into some crazy color squares, eventhough sounds still perform correctly. It’s kinda annoying for me. I love the way Khan’s academy organise teaching procedure. But the crash led me to the 3 stars rating.

Barely functions

Ipad air 2 user. A lot of the math features don't work when doing the tests. Very annoying. Was hoping this would be better than using my chrome app but that will have to do when I can't use my iPad because the app is unusable.
