It worked really well when I tested it, there were a few apps which I thought weren’t really necessary on an AndroidTV platform but other than that it worked great. However, this unofficial build is quite out of date now (Sept 19) so until I get around to building /e/ rom for fugu myself I suggest using the Lineage fugu build, it gets update every week or so, its very minimal and you dont really need microg on tv to be honest, just put on f-droid & Aurora Store and youre set… But keep in mind this unofficial /e/ build has nougat, oreo and pie rom where lineage is only Oreo if that makes any difference.
