If our team has requested collaborator access, please take a moment to review the notifications in your Shopify Admin. You should see a request from either the email domain @fastforwardapps.com or from Website on Demand Studio, LLC. Taking action on these requests ensures smooth collaboration and allows us to work together effectively on your Shopify store.
If you're not sure about collaborator requests or want to learn more about how they work, Shopify has a helpful guide that can answer all your questions.
