In case “does not save changes” means the checkbox is not editable, it must be either the case that security prevents it or the data view is set to non-editable. I believe there are no other options. and my gueass would be the first.
The another way, you can create a helper attribute into the domain model, and using microflow change the value of the associated entity’s attribute or you can call the microflow for the Attribute in the Domain model itself if it is predefined. Hope it will work.
it will be more helpful if you attach the screenshot of the issue.
