Why isn't BooksCloud allowing me to add books?

If you get the error:

Unable to create delivery profile. The maximum number of profiles (100) for this shop has been reached.

The issue is the number of delivery profiles your store has. The store has reached Shopify’s maximum limit of 100 delivery profiles, so Shopify is unable to create a new profile. 

Quick fix:

        1. Go to Shopify Admin → Settings → Shipping and Delivery
        2. Delete any outdated or duplicate delivery profiles
        3. Uninstall BooksCloud and reinstall it
