Here’s how to accept collaborator access for a Shopify store:
If You’re the Store Owner:
Check your email – Shopify sends an email with the subject line “Collaborator request from Magical Apps.”
Click the link in the email.
Log in to your Shopify admin if prompted.
You’ll land on the Users page and you should see a Pending collaborator request from Magical Apps Collaborator. Click anywhere on this line to select it.
Click the Accept Request button at the top-right.
If You Don’t See the Email:
Go to Settings > Users in your Shopify admin.
Look for a Pending collaborator request from Magical Apps Collaborator and click anywhere on this line to select it.
Click the Accept Request button at the top-right.
