This issue arises when either the trial period of your Development plan is expired. Or if your plan is not auto-renewed from the Shopify end. Contact us at shopifysupport@xecurify.com to resolve the plan upgrade issue and get smooth functioning of the SSO – Single Sign On Application.
Note: We provide a free trial only on the first installation. If you have uninstalled the application earlier and reinstalled after some days then free trial won’t be applicable.
