Hmm I wasn't aware it "fixes" titles as well... I am using it on Smart Tube to have better thumbnails, do I have to activate this myself to correct titles as well?
Anyway 99% of my ST usage (aside watching videos, as in, adding stuff to watch later) comes from my Shield TV home screen, I add stuff there to "My List" Shield row based on my recommendations row... And I am pretty sure DeArrow does not work there, only within the app :/
