Collaborators have the ability to edit a site theme
The Themes Editor allows you to easily update the styling of your entire website within seconds. Site collaborators do have the ability to edit custom themes for sites that they are shared on, but they can not use the collaborator themes on one of their other sites.
⭐️ If sharing themes is something you'd like to see in the app, please reach out to the Support Team at help@onuniverse.com and let us know!
