Apple changed something in watchOS 10.1 that means the time is missing (it is displayed by watchOS rather than by the app). However I have somehow worked around it in the code and released a new version of the app a few days ago.Why is the time gone? Is this a watchOS 10 bug?
So please update the app from the App Store. As usual you will probably need to update the watch app as well because Apple often do not update the watch app when you update the iPhone app. To do this go to the App Store app on the watch and install it from there. Do not reinstall the WorkOutDoors watch app by using Apple’s “Watch” app on the iPhone because doing it that way will lose the data in the watch app.
I assume that it is a bug in watchOS 10.1 because I thought that Apple forced apps to show the time there, but maybe they are being more relaxed about that now. Possibly as a concession to the watch face apps so they don't need to use hacky ways to remove the time.
If it is intentional by Apple then in the future I may make it optional as to whether to show the time there. Or maybe allow a different metric to be shown there. However I will wait a while before deciding because they may fix it in the future. If it is still possible in watchOS 11 then it may be worth considering.
