In app tutorials don't work

I'm trying to learn After Effects; after Animate screwed up and deleted my save file, I want to focus on something else, but I literally can't use their tutorials. I just want to know how to remove an effect from the timeline after a certain point (Like after five seconds, the effect disappears.) But I can't find anyone explaining it online, other than how to remove the effect from the entire timeline itself, which isn't what I want to do. I assume the answer is so incredibly simple that it's not found online, so I wanted to look at one of the tutorials and find the answer without asking people a potentially stupid question. 

Now I find out that the in-app tutorial button is just a bad prank. Because it does literally nothing. I restarted the app and my computer multiple times, and it just won't load anything. I'm just flabbergasted that every single Adobe product is having this many issues, like.. really? The in-app tutorials don't even work? Why is the option even there? I have no idea how to use this thing, and I can't even learn through the app. 

I'll look up tutorials online, but being able to visually see what to click on the screen and read why is much easier and interactive, so really why won't this work? And what's the point of the option if it doesn't function?
