Alexa Developer:

The Alexa Voice Service is moving to Amazon Trust Services (ATS) certificates for all AVS endpoints. Because of this change, all Alexa-enabled devices and applications must support certificates vended from ATS by June 15, 2018. Your device or application will not be able to connect to AVS if it does not support ATS certificates after June 15, 2018.

We recommend testing that your device or mobile application successfully connects to AVS endpoints using ATS certificates. Please follow the instructions listed on the AVS Developer Forum to learn how to complete testing and upgrade support for ATS.

Does that mean we can’t use let’s encrypt certificate anymore?

No, sounds like they’re asking vendors and developers of third party hw and software using Alexa to verify that they can handle the new root certificates on Alexa’s side.
