By default and regardless of TV Guide Service subscription status, all Tablo apps will show 24 hours of data within the Live TV Grid guide.
However, customers with active TV Guide Data Service subscriptions can enable an enhanced Live TV Grid guide which displays all 14-days of data on Tablo apps for Roku, Amazon Fire TV, & Android TV.
Simply go to the SETTINGS screen in your Roku, Fire TV, or Android TV app and enable the 14-Day Live TV Grid feature.
If your streaming TV device is older, or if your network is slower, this could slow down navigation within the Live TV Grid. If you find this is the case, you can easily disable this feature and return to the standard 24-hour view.
