I've been getting user reports of getting a black screen with a red X when they start my app (dwMap) on certain Vivoactive watches.
Here's a screenshot of it, send in by a user:
Searching the forum it sounds like it's been seen with other apps on the Vivoactive. I cannot reproduce it on mine (and the Vivoactive is my main test watch). Users say they have the latest (3.20) firmware.
Any ideas?
