Patrick Koerner Thanks for your reply.
As mentioned in my earlier post, you can continue to sync your account via IMAP which is Email-only, and the Google permissions page in the browser will only request Email permissions. Nothing has changed in terms of how the account syncs (IMAP) only the use of OAuth instead of Basic Auth. This is starting in version 16.15 (latest Prod release). In 16.14 the permissions page did mention Drive for IMAP accounts and that has now been changed, thanks in part to the feedback from posts like yours.
The new Google Account support which syncs Email, Calendar, and Contacts, does require Drive permissions for sync of attachments in this account type. If you only require IMAP for syncing Email, you can continue to use IMAP instead of the new Google Account support. If you have any questions about setting up accounts in different ways, please reach out via in-app support (Help > Contact Support).
