Just tried again tonight and it seems like it's now fixed. Presumably whatever file was needed has been put in the right place on Apples server.

Raised radar ticket FB8293243

I've now tried a series 3 watch and it works without this issue.

Also having this problem. I see that's it has happened in earlier betas for watchOS 3 and tried some of the solutions that worked back then, but haven't managed to resolve it as of now. I'm using Apple Watch 5 as my test platform....I might try a series 3 that I still have and see if its related to specific model?

Add to Forms also Pickers seem to not work on a view in TabView set to use pages

Hi, I have a very similar issue where a certain view in my TabView basically seems to prevent scrolling to other pages. I can scroll onto it from another page, but once there I can't leave. It seems to be related to the actual content of the View embedded in that page. In my case the problem page contains a Form, but it seems its the Section blocks that are causing the problem. (I convert the form to a VStack, still doesn't work but as soon as I remove the Sections it does).
