H1B Case Received Status

Upgraded transfer petition to premium on June 8, did receive the receipt notice but status hasn’t changed since, it’s been showing as below in my.uscis.gov, I have never seen this kinda status in previous filings. Has anyone come across this status before? Any help will be appreciated. “We received your case You do not need to do anything at this time We will let you know if we need anything else from you as we continue to review your case. #h1b #premiumprocessingh1b EDIT: Case status got updated on the site on 15th day.
