Firmware update 4.6.509530.43

Hi All. Where can one find the firmware upgrade file for the S10. We have a ton of streaming issues with 4.6.415145.35

Hi mworthen,
The products let you know when an update is available.
However, you can also check by selecting the gear on the app home page beside the product you want to check. Then select Speaker info, scroll down and if an update is available then it will be shown against Firmware version.
Hope this helps.
