Task just contains link to GMail - not to the Mail
just tried to create a new task from the GMail Add-In for a received mail.
Inside the Mail, I click on the button to create a task - but the add-in just generates a link to GMail itself (Inbox).
But the link should lead to the E-Mail itself?
Do you have the Gmail Labs feature "Preview Pane" enabled? As this can block our extension from working at all, or sometimes cause issues such as this.
