Hello @Tablue, and welcome to the Community.
You can try power cycling your Tablo, or uninstall and reinstall the Tablo app on your Roku.
That was happening to me also. I removed the app the added it again as that is the only way on a Roku to clear the cache. It works now just fine.
Had the same issue, removing and readding the app did not fix it for me. I had to launch a non-Roku client and change the Guide Options from Favorites to All Channels to stop the Roku crashes.
Roku app version 1.3.0-734366
Selecting Guide Options on the guide crashes the app every time
Did this update fix the issue with the random OTA channel order?
No, the Favorites list is still scrambled.
A fast follow-up release is rolling out now (version 1.3.1), which addresses the sort order for favorites as well as the inability for some users to select and use the Guide Options button, along with some other smaller fixes.
You should see the update shortly, but if youād like to get it right away, navigate to the Tablo app on your Roku deviceās home screen and hit the star button (*) on your Roku remote. Then select āCheck for Updatesā.
Random order of OTA channels has been fixed. Thanks!
