Have you had experience publishing applications in official app stores?

Experience publishing applications in official stores such as Google Play or Apple App Store includes several key stages:

• Preparing the application: configuring the manifest, icons, screenshots, description.
• Creating a developer account in the store.
• Building and signing the application using the appropriate certificates.
• Uploading the application to the developer console.
• Filling out application information, setting prices and distribution regions.
• Undergoing store review and moderation.

This process requires attention to store requirements and may include fixing comments after review.
