I don't think I've ever gotten an automatic update. I always download and extract it to a USB stick and install it that way from here: https://www.sony.com/electronics/support/televisions-projectors-lcd-tvs-android-/xbr-65x930d/downloads
Is there any way to tell when the update rolls out to specific areas or specific sets? My 930 still shows the previous version and checking for the update produces no update available. I do have it set for automatic updates and by this date I would have thought it would have been picked up.
