Updating fields in portal form widgets

[bonsai]

On the platform, when you update a record, the fields are automatically updated if the same record is viewed in another browser.

However, the same process doesn't seem to work on the portal.

Is there a way to tell if two users are updating the same record?

if you are talking about when form is opened in portal using form widget, then it's not supported by ServiceNow.

that feature only works in native and configurable workspaces on form.
