As an example, there's only one app store made super visible on this laptop: the Google Play Store with Android apps. You open it and on the home page it advertises the Disney+ app. Cool! I'll install it!
It takes forever and runs like crap. Dragging it across the screen makes it lag behind the cursor, and loading a single other webpage makes the video stream constantly freeze up.
But if I go to the Disney+ website, it works great, with smooth video. But it recommends I open it in the app! 🤦
