Regarding your concern about "Calendar Sync Pro," it sounds like the application is using a method of authentication known as OAuth2, which requires periodic re-authentication to ensure security. Unfortunately, if the application is designed to ask for authentication every time it syncs, there might not be a built-in option to change this behavior, especially if the developer has implemented it for security reasons. You can check the application's settings or contact the developer for potential options to reduce the frequency of authentication requests. If there are any updates available for the software, they may also provide improvements or changes in functionality.
