Judge orders Epic, Google to hold settlement talks | Epic vs Google

Could anyone more familiar with the case provide some insight? I thought there was no restriction on alternative app stores. I have F-Droid and Aurora installed, and I didn't need to do anything special, I just installed it from the project's web page and that was that. For the second, the judge already mentioned that Spotify already handles its own billing.

So what exactly is Epic's complaint here? Is there something on the newer Android versions that prevents this? I'm on an older Android version (11), so I guess I'm wondering if the newer Android versions will cause me issues.
