Shopify Extension no longer working in CRM

Shopify Extension no longer working in CRM

Zoho CRM and Extension are no longer working properly. We have used Shopify Basic for years. All of the sudden it stopped working, then started working again, and now no longer working again. There are several ways for Personal Information to sync from Shopify to Zoho CRM, and even after showing via several screen share sessions and screen shots, Zoho CRM is in denial that for years we did not have a problem. They even said that data is unable to sync via a Lead, which is bizarre. No matter what we share, they continue to stall, won't share data that supports their claim, but we consistently share the facts that are ignored. There are several ways to get the data, Zoho Flow, which is no longer working correctly nor Deluge. We did nothing on our end, but nothing is working and Support is ignoring our requests to simply fix what no longer is working. If data is unable to sync from Shopify to Zoho CRM, the entire platform is useless to us. Any suggestions?
