Zoho authentication with Shopify

Zoho authentication with Shopify

Hello

We started using the the Zoho campaigns facility on the free plan. We went through the process of associating our account with Shopify.  However when we did this we received a popup window saying that it was successfully associated, and if window does not close in 10 secs, we should close it and reload Zoho compaigns. Well the window did not close, we reloaded the Zoho campaigns page.  We just cant seem to get it authorised all though the Zoho campaign app is visible in our Shopify app section on our store terminal.
