Hello Apichai Jaihao and everyone!
Thank you for reporting this issue to the Q&A forum.
From what you shared, after updating to a newer OneDrive version, the sync status icons (checkmarks/cloud icons) are no longer showing in File Explorer on your Windows, even though files still sync normally. You also mentioned that some related functions, such as sharing, are not available when the status is missing.
From recent reports, this behavior appears to be affecting multiple users at the moment, especially on newer OneDrive builds, so it may not be specific to your devices or configuration.
In this situation, I recommend sending feedback from the OneDrive app through Help & Settings > Send feedback or via Microsoft Feedback Portal, so the issue can be raised directly to the product team. Since this is a user-to-user community forum, we can only share suggestions based on what we have found and experienced, and no one here can check or change anything on the backend.
In the meantime, please also keep both OneDrive and Windows up to date, as this can help ensure any upcoming fixes are applied once they become available.
Thank you so much for your time and patience. Hopefully this issue will be addressed soon!
