For instance, when I first logged onto OneDrive through the app, I initialized the synchronization process. At that point, both the app and the cloud storage repository held 100 tracks. Later, I made some additions and deletions within the cloud storage, and then I refreshed the app by clicking on the 'Scan Cloud Storage' option. To my surprise, the app reported a higher track count compared to the actual number in the cloud storage. Upon closer inspection, I discovered that the deleted tracks still appeared in the app's playlist, albeit playable. It seemed as though the songs persisted due to caching or some other reason. Nevertheless, I was curious about whether there existed a method to ensure that the app's playlist and cloud storage's tracks remained in perfect sync after each addition or deletion operation.
