So far, it looks like 6-7 days.
I’ve received emails from a couple folks who have submitted tickets to Google about the Gmail receiving issues. After 6-7 days, each person has received this message back:
Thanks for bringing this issue to our attention. We have forwarded the information you provided to the appropriate team for further investigation. We appreciate your patience, and we apologize for any inconvenience this may have caused.
The Google Team”
So, it sounds like even their response to a ticket support request is a form letter, and I bet they have it configured to auto-reply after a period of time to get folks thinking they were actually looking at the problem during the period of no response.
Google is crafty. So’s the devil.
