Due to recent incidents with some urls in emails to Gmail / G-Suite being flagged as "malicious", engineering teams have continued to work on root causes of this issue, improving anti-virus scanning and limiting the impact of potential future events.
As a result of this work, files linked in notification emails with the following extensions will no longer be directly downloadable from notification email but will still be available in the Inbox product:
doc, docx, xlsx, docm, xlsm, img, exe, html, htm, php, js, zip, gz, 7z, rar, z, zls, tar
Attachments of other filetypes will still be linked in email. Attachments to normal outbound email from the Messages product are not affected by this change.
