If you're seeing the error message "Failed to activate product" when clicking the Activate button, it’s likely because the product is in "Draft" or "Archived" mode in Shopify. Currently, Mayple does not support activating products in these modes.
To resolve this, mark the product as "Active" in Shopify first, then try activating it in the Mayple app.
