UPDATE Mar 15, 2022: With watchOS 8.5 release, my Unity watchface is back to normal!
Recently, the Black Unity watch face on my Apple Watch 5 went mostly blank on me. This is what I see on my 44mm Apple Watch 5 (standard). Only the seconds hand spinning around.
I’ve rebooted. I’ve also deleted it from my Faces in the Watch utility app and re-added it. No luck. Suffering through the un-pairing and re-pairing process is too much effort for any watch face, especially without assurance that it would resolve the issue.
I suspect 1) the bug is associated with the face being the first to use raytracing, and 2) the bug was introduced with the recent watchOS update (8.4.2). Note the coding-style labels showing the the Edit interfaces.
If you’re experiencing this issue, as well, consider submitting feedback to Apple at https://www.apple.com/feedback/.
Here’s to hoping an upcoming update will fix this issue. That watch face looks awesome and celebrates a topic about which I feel strongly.
