I'm writing this here for an Issue i'm facing in App Preview after submitting Extension App to Microsoft MarketPlace. The Add-on is in preview mode but we are facing issues when we try to install app from App Preview.
Error Details: "The extension failed to be deployed successfully. View the error details for more information and then deploy again."
Error Summary: "Deployment failed. Errors: App ID : xxxxxxxxx-71ed-xxxxx-834b-7327fxxxx2ee Message : { The extension is not available for your release. Check the country and version availability in the extension marketplace. } - Job Id : xxxxxxxxx-71ed-xxxxx-834b-7327fxxxx2ee"
We spent 3+ months developing this specific Add-on and when it's time to publish it, the Marketplace support team response is very unprofessional. We opened support tickets couple of times but just got automated emails and no response yet from Support Team Lead assigned as well.
i'm writing here to GET opinion from community about who to contact and how we can escalate this issue as soon as possible.
