Hi, I wanted to share a task with a link to an external user. prior to doing it, I tested with my personal email account. I specifically wanted to check whether Google Drive files attached in the task where accessible to the user and if Drive's permissions where correctly applied by Google. However, I incidentally noticed that once a user receives a link to see a task (read only), he/she can also access the project Overview tab and can access it. I could then see all the activity on the project (it was a project I was starting, so limited activity, and I may be wrong), including other members and files added. So, I think that in any case an invitee with a share link should not have access to the project overview, or at least put it as an option.
Thanks, Alex
