I sent a note to Amazon and this is what they responded with. Kind of disappointing and senseless.
Thank you for contacting Alexa Support Team. I understand that you've residing in Canada and got 3 Echo Dot devices. The functions named timers, reminders and drop-in functions are not working on these devices. I would like to inform you that as of now most of the Alexa services are available only in United states of America, United Kingdom, Austria and Germany due to the restrictions of functions in other countries. Alexa drop-in and Alexa to Alexa calling and messaging feature is currently available only for the Alexa users residing in the United States. Also you're facing issues with the other services because of your country of residence (Canada). I'm sorry, as of now all the Alexa services are not available for Canada due to the restrictions of your residential country.
