I have only received an update within a day once and then it was withdrawn. So if it isn't luck what would you call it?

Just in the last four years, the firmware updates installed within two or three days max... that's all... That's why I say I'm not particularly lucky... ;-)

But actually...thinking about it...maybe there just weren't any announcements back then...":good surprise"...the anticipation only started when others announced they'd received it. ;-)

The announcement for the last WiiM Amp firmware was on December 26th. I got it on January 13th

(I might just be wary of the "in two weeks" etc... I'm always wary of announcements that aren't followed through... Perhaps I appreciate "pleasant surprises" much more.)
