I'm not sure what's new in this update yet, I stopped home at lunch and saw the prompt to update and started the update before heading back to work. I'll update this post when I get home with any changes I see. Hopefully it's the 7.0 update!
Update: Unfortunately, no 7.0 (Release notes: https://esupport.sony.com/US/p/swu-download.pl?mdl=XBR55X850C&upd_id=11218&os_group_id=18). The only difference I can see so far is that it's now on the May 1, 2017 patch level; too early to tell if performance was actually improved. I'm in the U.S. btw.
So I bought two these since it was a great deal Harmony hub remote
What I have Nvidia Shield & Mi Box LG 4k TV & Insignia TV Google Home
Living room I set up the Hub with my computer cuz I heard that installation is alot easier & it read my Nvidia shield TV & 4K quickly.
The problem I have is the harmony remote, I heard the remote works better it being on Bluetooth connection with the shield but it could never read it.
My only grip with the remote is the Back button doesn't work, I have to use to the Exit button.
How do I make this work? I even tried the button mapping and it says it won't ready it or maybe I'm doing it wrong.
The same problem with the bedroom on my Mibox tv
