On my Sony TV using Tablo 2.0, the Settings screen indicates that the guide was updated two days and 5 hours ago. If I try to update it manually, it just keeps spinning. The Recording recent very often presents faulty information.The only way to get things corrected is to delete and reinstall the app.
But on my PC at http://my.tablotv.com/, it indicates that it was updated a few minutes ago!
I opened a ticket with Tablo but I would like to know if other users experience the same behaviour.
