Another new software update is currently rolling out to the Amazon Fire TV Cube. This new update comes less than a week after the previous update arrived. While that update brought a few new equipment control options, this latest update is likely just fixing an issue that was either left out of the last update or introduced by the last update. The new update a carries the same 188.8.131.52 version number as the last update, but increases the build number by one digit to NS6222/1537. Scanning through the various UI elements, I was unable to find any differences between the two version, but be sure to comment below if you find that something has been changed or fixed.
