Same here. Last build upload with the "internal" tag was Jun 12 for us. After that, the next upload was on Jul 9, and there the "internal" didnt show up anymore. This fits to your Jul 3 observations. We didnt change anything on our CI and older commits which used to work properly, are not working now. Neither Testflight's 'testFlightInternalTestingOnly', nor XCodes manual distribution with "Testflight internal only" set the "internal" tag in Testflight.
