Employee and Manager users cannot see project milestones

Employee and Manager users cannot see project milestones

Hi Zoho team

I have been testing access to one of my projects before I allow the project team access.

I have one milestone set to 'External' and my test user added to the project, however the test user cannot see the milestone. 

I changed the user's group from Employee to Manager as well. Both did not work. Am I missing something?

Any help would be great.

Cheers

Joel
