3rd party widgets not loading

Today's build, can add a third part widget, (Ambient Weather) using what I'm guessing is the old picker and it is added to a second tab normally. I close the app and reopen it and get the message that the app not found.

Still happening after the update last night. If I uninstall the app then install the latest build then 3rd party apps will load normally with the old pick list but only once then this happens again. Mike
