Same here. When I try to rescan the TVE channels it just comes back saying zero new channels to scan. Everything else that is TVE works fine but for some reason FOX never even shows up.
I have posted about it and submitted logs via email but no response of any kind. I assume they don't have a solution yet because the devs are usually on top of these things to sort it out.
Luckily I have OTA for the locals. If it were an issue with the cable only channels then it would be more of an issue for me.
