I have added a collaborator for my Pinterest app, however, when accessing the colaberators account and clicking on the application there is no \'authorise\' button or anythi
We had the same problem. You need to at least add two co-workers, one as collaborator and one as tester. These must be different people. And then, after some while (!) the authorize button has appeared.
The co-workers need to accept the invitation as well, of course.
After submitting, it will take some weeks (!) until you get the approval.
