Does not work
Response from developer
Permissions are required to play music during intermediate notifications and the final notification, but please rest assured that no information or data is being transmitted. Additionally, if it only vibrates at the end, it's because the silent mode switch next to your iPhone is turned on. Please turn off the silent mode here (so that it is in the metallic state instead of orange) and try running the app. [Addendum] It appears that in iOS 18, there are issues where voice reading aloud is not functioning and music is not playing. We will investigate whether this can be resolved through an iOS 18 update or by our own measures. We apologize for the inconvenience and ask for your patience during this time. [Addendum 2] I will wait for Apple to fix the issue with the iOS 18 update for a while. If it still isn't resolved, I will attempt to fix it myself, so please bear with me for a little longer.
