The WTVQ sale hasn't closed yet, Scripps only took it over via a LMA, so it's not listed on TVPromise for Lexington
For the former Ion stations:
It doesn't show WXPX/66 Tampa, but it does show KMCC/34 Vegas and KUPX/16 Salt Lake City
EDIT: They finally updated the streaming server, WXPX is affected too, however as of now the ex-Gray stations in Colorado Springs and Twin Falls are still active even though TVPromise lists them, which would bring them to the 54 listed in the press release:
