Although I was able to install the 5.3 update on my Apple Watch 2, my wife can't install on her Apple Watch 3 because she has insufficient storage. According to the Watch app on my iPhone my AW2 has a storage capacity of 5.2 GB with 2.3 GB free. On my watch I have zero songs, 24 photos and 17 apps. My wife's AW3 says that it has 4.3 GB capacity with only 739 MB available. She has 27 songs, 24 photos and 5 apps installed. I have a hard time understanding how her 27 songs could consume so much storage. We have rebooted the watch, but the storage figures remain the same. I know I can restore from a backup, but I'd like to know if there's a better, easier way to fix this.
