Apple Watch App is missing

Dear All,

I have an iPhone 6S running iOS 10.2.1 (14D15) - on my Apple Watch (1) 3.0 (14S5315a), the App is not appearing on my Watch. I uninstalled, restarted and installed the App several times. Still no change.

I would assume that the BETA OS might be the problem, do you have any information on that?
Any other suggestion what I can try?

Oh, I use the universal APP in version 2.18.1


I have the same problem. Did you managed to solve it?

Kind Regards, Damjan
