When Amazon added the ability to send and receive calls and messages through Alexa devices last month, they did not include a key component, which was the ability to block certain people from calling or messaging you. They have now corrected that misstep through the most recent update of the Alexa app. Now, if you go to the contacts section of the Alexa app, at the bottom is a new “Block Contacts” option. When selected, you’re given the option to block specific contacts on your contact list from calling and messaging you. The new Alexa app, with the new blocking option, seems to only be released to iOS devices at the moment, but I’m sure Android devices will gain the new app with this new ability soon.
