Did you see this on their front page?
NOTE: If you are using version 110 or 180 of our driver and your triggers have recently stopped working - this is due to a firmware update that Amazon is rolling out to older Echo Dot (Gen 2) devices. You will need to install our V200 driver, which can be found HERE. v200 REQUIRES OS3. You will also have to remove the old driver from the project and then add the new driver, so please be sure to copy over any trigger programming that you want to retain into Macros, or backup your project file, and then you can copy/paste the programming from the backup using Virtual Director.
Not sure if this would help or not. I'm still on OS 2.10.3 Guess I need to upgrade.
