Channel 622 down for weeks

There are some channels that have had long standing issues and I'm not sure if anyone is checking channels or if they are just too busy to check. Most of the Chinese CCTV channels 1,2,3,4,5 and 6 are either down, looping or just running recorded video which has nothing to do with what is actually on those channels at the time you tune into them. I noticed channel 622 along with some of the other British channels has been having issues as well although 622 has been literally black screen for weeks, no video, no audio. I don't know if the problems relate to the server, the cloud or the video player or the technical issues, links or service providers ? I have noticed that the STB Emulator Pro app has been getting frequent updates which may provide some hints as to what might be providing some of the issues but I try to check weekly on any new updates.
