It most likely on WU's end. I have given up worrying about gold stars and Wundermap. WU seems to be completely oblivious to all the issues we are all having. Someone from WU had posted that they had tightened their QC and this may be the issue or not. I also report to Ambient Weather and that also sends to PWS. As long as I can see my data at Ambient I am okay. Ambient also has Android and IPhone apps as well.
