Applying a profile in Vela will overwrite the existing attribute data in your listings with the attributes contained in the profile. This ensures consistency but may replace previously entered information.
How Profile Updates Affect Listings
When you apply a profile, all attributes within that profile (e.g., pricing, tags, variations) replace the existing attributes on connected listings.
You can still edit individual listings after applying a profile.
However, if you edit and reapply the profile, it will overwrite any manual changes made to connected listings.
