Missing. Channels

Only on my Apple TV 4K boxes does the tv guide not go past channel 3491. The 4000 channels are the tvgo channels. They appear on all other devices including, tv’s, fire stick’s, iPhone and iPads. Because of this, the free streaming channels like, unsolved mysteries etc…are not viewable. Error TVAPP-00144 pops up. Why 2 different guides?  Yes I am on my home network and all is updated, restarted, rebooted… Phone Tech support said it’s only available on devices that are portable. Sorry but my Samsung tv’s are not portable so that reason is incorrect. Again, the tvgo channels missing in the guide is directly related to not being able to watch those streaming channels, ie 4000 and above.  Solution?
