I believe that OS 6.2.8 is when you get the new Home Page UI.How are you on 6.2.8? I've been stuck on 18.104.22.168 forever it seems. Checked again today and no update.
Anyone else have a version of OS 6 newer than 22.214.171.124?
I have four (4) FTV4K devices and they are all on 126.96.36.199. The update will show up eventually.
