Apple Watch error ‘Sitemap without title’ after 3.0.8 (30)

After installing the newest Openhab app using Testflight, I get this error. Resyncing or force quiting does not change anything. Watch-sitemap, loads perfectly fine on iPhone.
Any suggestions?

This is the header of my sitemap:

sitemap watch label="Watch G&J"{
	Frame label="" {
		Text item=ShortDate labelcolor=["yellow"] valuecolor=["white"] label= "Home Control" icon="openhab"
	}

Did you sync when you were connected to your home network or through your mobile network ? I had a similar problem when I updated the OpenHAB app (testflight) connected to the mobile network. The syncing process did not allow me to use my sitemap. I switched on the VPN on my iphone, and suddenly the sitemap appeared. But I am not sure this was causality or just correlation ;-). Did you visit the parameters menu on the OpenHAB app iphone and select the sitemap for the apple watch ? Hope it helps.

I am on mobile indeed. You are right. When switching on the VPN it works. But only then!
Switching off the VPN and after resyncing, the problem persists.
And I reselected the sitemap in the IOS app. Did not solve the issue.

It still is a bug I think, which should be resolved. Thanks anyway.

I saw you opened an issue on GitHub. I am eager to have it solved.

Yes I did and I also hope there will be a solution in reasonably time. For the time being I returned to an older version.
