Issues with mobile notifications for some Grid customers

Technical Summary:

On February 15th at 12:30 PM PT, a database change was deployed to help us move to a new system. The change in systems resulted in push notifications not being delivered for some Grid customers. Between February 15th and 19th, we received reports of missing notifications from Grid customers which were attributed to a bug and further investigated. On February 19th, our team identified the root issue affecting Grid customers and reverted the deploy. By 6:30 PM PT the revert had been fully deployed and push notifications were working normally again.

We’re very sorry to those affected for the disruption. We’re investigating the root cause and making plans to ensure this doesn’t happen in the future.

We have resolved the notification issue and everyone should be receiving mobile notifications as expected once more. We know this was really disruptive and frustrating, and we're very sorry for the trouble. Thank you for sticking with us.
