As a normal part of troubleshooting, Zentail Support staff may request that you submit a ticket regarding an issue with a certain channel to that channel's support directly. Normally this is done in addition to Support staff filing a ticket about the same issue on your behalf from Zentail, the primary purpose of this is to reduce how long the delay is for a reply from Google, but also to increase attention on the case.
