I recently publish an app on playstore and appstore. and I want to make updates to the one on the stores. Are there any additional steps to do this or does google or apple do this automatically for me.
Your title and your actual text don’t really match. What is your question exactly?
I’ll be releasing an update is there something I need to add on my code or do the stores automatically notify the users who have an old version of my app?
Upload it to the store, release it, then your users will automatically download the update or see it in the list of updates in the store.
ok so no need to configure anything additional thanks will try it.
