Hi @squaleon!
Grabbing a response to a similar question for your first question
currently when you eject, you get an “ExpoKit” project. this is a bit different than what the “bare” workflow available to you when you initialize your project. basically, ExpoKit is like including the Expo client in your app but rather than having the Expo client app where you can sign in and open your apps in development, it just points directly to your app. this has some nice benefits - everything works roughly the same as when you were in the Expo client. but it also has some downsides (discussed in the ExpoKit 2019 blogpost ). bare apps, on the other hand, are just regular react-native apps with as few or as many of the expo sdk packages installed as you like.
- Yeah, you can use OTA updates with Expokit, but not with the bare workflow yet
3 Not super familiar with fastlane, so I can’t give you more information on how best to handle js updates in bare
4 Similar to answer for number 3, not super familiar with it. You’d have to go with a third party library for push notifications in both bare & expokit
