Huge amount of items missing off AH after today's reset

I've seen a mention of it in the WoW discord and people are discussing it on one of my servers trade chats. I can confirm that items I listed last night did not sell and are now completely missing. Very common materials like popular bars and cata herbs were totally absent from the AH.

Not sure what to do but hoping to confirm the issue and raise some awareness. What would be the best way to notify Blizzard of this issue?

5/26 3PM Central Edit: No update or returned item. The link to submit a ticket for this specific issue is dead so I had to submit a general ticket with an estimated wait time of 4 days. Seems very widespread across my main server.

5/27 3PM Central Edit: Received an update to my ticket that I need to report it as a bug. "Greetings!

This is Game Master Sylcraes, following up on your recent reply about this issue.

At the moment we do not have any confirmed bugs related to Auction House listings disappearing. If you believe you are encountering a bug, you will need to submit a Bug Report via our in-game Help menu, which should show up as a red ? mark by the system menu. These reports go directly to the Quality Assurance teams, who are able to use the information to further investigate the issue.

I understand this wasn't the response you were hoping to receive today, however I thank you for understanding and wish you a wonderful day going forward."

6/2 4PM Central- Final update: After putting in 5 tickets one of the other sellers on my realm got a GM who looked into the issue. I believe everyone should now have their items restored. https://us.forums.blizzard.com/en/wow/t/item-lost-at-ah/978501/13
