I'd never contacted Chat before today, but they told me similar. Said mine is expected to be Awaiting Shipment _by_ 9/9... which I confirmed meant it will be "built" between now and 9/9. I have modules and tear tag, but no official built email. I'd read somewhere that some factory-installed...
I noticed this when viewing the backdoor site via mobile... the build week box stopped appearing. I was worried I'd been bumped as well, but when logging into the site on a laptop, the build week tile still appeared. Yours sounds like it may be a different issue though... but good luck!
