Today I have been getting a full storage message on my watch. When I look up the usage it shows 0 available and 12.2 gb used. It also shows that I do t have much being used by apps, and I have no photos or music. I submitted feedback, but is anyone else having this issue? Or does anyone have a workaround as I can not delete anything or find out what is using the storage. I’m afraid I won’t be able to update the OS as there is no room when v3 is available.
Storage on Apple Watch 4 watchOS 6 says full
amazingly I am on watchOS 6.0.1 in 3 October 2019 and I am having the same problem you reported in June with the beta.
Remarkable how Apple persist on not listening to neither developers nor customers alike.
I was told a couple weeks ago by Apple Support that this is a known issue but the next WatchOS update will fix it.
