My guess is that this could be a feature that recognizes an audio signal from the tv and will switch back to that input if you're still in the bluetooth input but I guess we'll all see in a few days.

Since the update on both IOS (iphone10 & ipad2) I can no longer access my Smart Speaker in the Bose Music App - it shows the device but says product not found. Also can’t re-add using the app either, as it does not find the device. The only way to connect is using pure Bluetooth to play some music. Very disappointing as only had the speaker for less than a week.

My firmware is still 7.0XX
But, with the iPhone app update, I can now control input from the app to either tv as source, Bluetooth, or Apple Music/Airplay 2.
im assuming this is the A4 functionality they are talking about.
Got the 700 with LG C9 OLED and AppleTV4k
I still have the 7 version on my soundbar 500. I tried to download the firmware from the website to install it manually but from the support site the new firmware is not yet available. Could you publish it? The link to download I’m referring is https://worldwide.bose.com/support/SB500FW

Well, it does say "you may not receive the update until May 12". I'd be more excited about this update if I knew what the hell A4V TV Detection was.

Still with 7.0.11...I guess this is the longest I have waited for an firmware update....not even sure if this is being rolled out everywhere?
does anyone know what happens if you don't receive the update by 12th May?
I'm guessing that most of us will see our firmware updated tomorrow night ... or a day or two after that. Personally I wouldn't try to manually update. I'd just rather it do its own thing. I'm pretty sure we'll all get it within a few days.
