Using the latest version of the app I'm unable to update the data screen layout of the MTB activity on my 255sm. It works for other activities like Run. And works on the watch. And after updating the layout (e.g. changing from 4 to 5 fields) it shows correctly on the app and I can choose what data to display in the fields. But when I choose a different layout (e.g.) 6 fields, it doesn't make the change.
