NOT a formula question - every cross-sheet reference in our account died on Aug 13, and reports/dashboards broke too

Question

This is not a formula syntax problem. Our formulas are unchanged and correct.

Smartsheet simply can no longer resolve references to other objects in our account.

Since Aug 13, every cross-sheet reference across the entire account returns

#REF / #INVALID REF / #BLOCKED. Formulas inside a single sheet still work fine.

It is not limited to formulas. Reports and dashboards fail too, with

"You do not have access to this item - permission settings are preventing

access to it, or it may have been deleted."

What we have already confirmed:

* Nothing was deleted. The Activity Log shows zero delete, edit, or

permission-change events in that window.
* Everyone sees it, including our System Admin and our CEO. Not a sharing issue.
* Creating a BRAND NEW reference also fails: "The source data is no longer

accessible."
* 94 sheets and 11 dashboards affected. The status page says

"All Systems Operational."

Support has not replied to any of our three cases (filed Aug 14), and our tier

has no live agent chat or phone support.

Has anyone hit this before? Did it ever recover on its own, or did it take

Smartsheet engineering to repair the account?

Here is the English translation of your message, written in a natural, polite, and helpful tone:"Hello, I can imagine how frustrating this must be since we are in the same situation. The reason I'm reaching out is that it's very difficult to connect directly with a human agent, and the AI counselor kept handling it until I finally got a receipt number. Although a ticket number was generated, the system keeps saying that the ticket number I inquired about does not exist. Could you please let me know through which channel or page you submitted your inquiry?"

I too faced the same issue when a sheet link failed and it returned "You do not have access to this item - permission settings are preventing access to it, or it may have been deleted."

Also scheduled automations are not running. I raised a ticket too
