Hi Kaleco, assuming you might not be using the command line (I don’t), and maybe just Animate. I started out as a designer making apps many years ago:
You are probably talking about Apple’s process of publishing apps. This is always difficult at the start, but once you set up your certificates the process gets very easy.
I just make one Distribution.p12 file as my main cert. Then I use one Ad Hoc profile for all my apps for testing on the device. I then make Distribution profiles for all my apps and when I publish to the App Store I just switch to one of those profiles and use the same password.
Apple’s Portal (App Store Connect) is now extremely slick. There are no bugs or anything. I find Google’s Console over complicated and buggy. I also rarely make apps for Android on Google Play anymore because the sales are nearly non-existant. iOS at least has potential for selling apps.
The only painful part of making Apps for Apple is that the screenshots take ages if you publish to both iPad and iPhone. Also things like videos have to be in exactly the right size. But both Apple and Google now have strict rules. Google has become far worse though - ridiculous!
Here is my latest app, all made in Animate and Adobe software:
