Sure. I’ve tested it with the Update Household process created by the Basic Register block.
The elements that are not saving are:
Marital status
To receive Blog posts by email
To receive Prayer requests by email
To receive Bible readings by email
All four elements of the “Refine address list privacy”, i.e.
Show email address
Show cell number
Show landline
Show address
I’ve not checked anything above Marital Status. I think they work.
Hope that helps,
Mark
