Received from Amazon:

"...beginning on November 8th, 2021, email access will no longer be supported for Alexa customers. This means that you will no longer be able to link your Gmail or Microsoft email account with Alexa to browse or manage your email, and any linked email account(s) will automatically be unlinked.

This change will also impact related email features such as email routines and email notifications. Additionally, we will no longer support email package tracking if you have opted into this feature to receive updates from retailers outside of Amazon. However, you can continue to ask “Alexa, where’s my stuff?” to stay on top of upcoming Amazon deliveries.
