I am getting near to finishing our Ionic project and submitting our app to the android and apple app stores.
My question is what happens when I want to make an update to the app content - do I have to go through the submission process to the app stores or is it an easy process?
Could anyone recommend a good link which discusses how to push an update to an app?
Yes, you upload an updated build of your app to the stores. For Android it will just be released, but for iOS your will have to wait a day or two for the review.
Google for “Ionic Deploy” and read what you find. This will give a good picture.
Be aware that 95% of what you are reading are for the old Ionic Deploy though. Functionality is the same, but technical details are completely outdated as the new one uses a whole new plugin and API.
