If you are encountering issues with SharinPix Image Sync when uploading photos via the Salesforce mobile app, here are some configurations that need to be looked into:

• Check if option Enable Image Sync has been applied to the SharinPix Album

The first thing that needs to be checked is whether the option Enable Image Sync has been applied to the SharinPix Album component on which images are being uploaded.

If you need help to verify this part, please refer to the following article:

Enable Image Sync for Lightning

• Check if Image Sync has been set up properly for the object on which photos are being uploaded

Another configuration that should be verified is the Image Sync setup for the object on which photos are being uploaded via the Salesforce mobile app. 

One step that can be easily missed here is the assignment of the SharinPix Image Sync's permission set (that is, SharinPix Image Sync Permission) to the user uploading the photos. For more information about the setting up of the SharinPix Image Sync, you can refer to the article that follows:
