As we know by now, a fix was promised to be released "By end of September" 2018 but, as Free Support ended on October 31, 2018, and as "By end of September" simply vanished shortly after from D-Link's Support Announcement (https://tinyurl.com/y8mw9ook), it is indeed safe to assume D-Link have chosen to silently renege on their commitment, - without any kind of compensation, buy-back or new cam discount offer. Sad !
Incidentally, Rev A datasheet 1.00 is dated 09/10/13, so it ain't very likely DCS-930A got discontinued "5 years ago", - just two months after intro !!!
Just saying !
..... Cheers
