After a 12 hour transpacific flight from San Francisco as United 888 just now, I was on approach to Beijing and when within range I dialled in to the ATIS frequency, absorbed the information and then duly called in to the Tower. I was given the necessary instruction, replied, and then the purple text appeared at the top of the screen telling me Tower was offline and it was switching to Unicom. I called out my inbound status on Unicom, but then got an On Guard from Tower. However, Tower was not available on my frequency list, and when I clicked on the airport itself only Ground was showing up with live ATC.
Clearly this is some sort of glitch, and wanting to avoid a ghosting that might knock me off Expert, I felt I had no choice but to reluctantly end the flight without landing.
Did I have any other option here? Would clicking WiFi off and on have restored matters, or is there anything I could have done on my callsign to alert the controller to my problem? I have read that people have used “ATCISSUE”, but I don’t know how legitimate that is.
Any guidance would be appreciated. I think this has happened to me once before at LAX, but on that occasion I just got a Check Help from Ground after landing (no On Guards while in the air, so I had no idea on that occasion that Tower was actually still active).
