We tried that and other hacks suggested but didn't get anywhere. But now we are past that and have our case number, done the medical interview and waiting to do the embassy interview.
I'm getting exactly the same issue. I can't update my timeline with the date NVC received our petition. It's saying it took too long which is exactly what happened; it took 91 days from the approval date!
I'm somewhat stunned but today we received an email from NVC saying they'd received our petition from USCIS and it was now waiting for data entry into their system.
We've tried that and the " live chat operative " cut us off twice. No idea how to get past this. We are now outside the USCIS timeline and still not getting any information from them as to where our petition is. We were approved February 1, 2023.
