No I have not, I saw it but it says F.20 is included, but I'd like to use F.21. Maybe if I flash it with lineage recovery it'll keep F.21? No idea.
Weird that n77 is disabled but n260 and n261 aren't. Most of the time on 5G nationwide, NSG shows LTE with either 2 or 3 CA. On rare occurrences it shows NR-NSA. Either way, it's always on n2, n5, or n66.
