Looks like it to me:
If that were true, the Trakt program addon would be available somewhere.
If it’s native to OSMC and in MyOSMC, I don’t see it.
Every article says it’s official for Kodi now, but you have to install it from the Kodi Addon repo.
The one on my Raspberry is v3.0.0.
Looks the same as the picture I sent.
Just 3.0.0 instead of 3.1.6
Same Kodi version running on my PC. That’s where I took the picture. Also where I went to the Kodi Addon repo and installed the Trakt program addon.
Did you see my screen shot above? That is from OSMC.
Settings → Addon Browser → Install from Repository → All Repositories → Program add-ons → Trakt
Post debug enabled logs so that we can see exactly whats what.
