If a power reboot on your playback devices and Router doesn't make a difference, then on your Stick try step 6 of this linked guide below (can't help with regards to an Xbox One because i don't own a Games Console).
If nothing still doesn't work, then it sounds to me something is blocking the Bonus Streams on your Router (perhaps a VPN ?).
I just noticed had same issue with missing red button games at bottom of Home Screen. Had no issues with this in past. I unplugged and restarted and they have all appeared now. Including future matches.
