I keep getting the message that my S3 watch storage is full but there's nothing that would explain what is taking up all of the space. I don't have any music, photos, or podcasts synced. I only have a handful of apps installed on the watch. I've unpaired and re-paired my watch a couple of times now and initially it has plenty of free space; about 4GB. But after 3-4 days it ends up completely full again. The Usage screen is of no help as there's nothing that explains the usage. I'm already down to just 50MB after re-pairing it a few days ago.
