i m not a lawyer yet this is what i believe based on what i saw with my own cases…
This message says “on june 26, we denied”.
So this means that this is the decision as of june 26 that you are able to see not any other decision taken after.
Sadly, whatever happens with our cases is not always uptaded on the website .
Just to give you an example, my petition was approved beginning of september, the website egov.uscis.gov you are referring to does not reflect this approval, just that they received my case on august 8.
There is this other website that i came accross as well myaccount.uscis.gov. 2 years ago this one showed things that the other did not yet this time around, it shows the same thing as the other one
Yet maybe try and see if you see something different.
Good luck with the visa process!!! Hope you ll get what you want!
