The next problem arose with the customer support. The support service sends an invitation to the client's email address. It is registered in the system. After that, he can log into the system. After entering, he sees other projects and tasks of other projects, although I should not see them. In addition, he can create tasks in projects, in addition to the support service.
How can I restrict access to customer support?
It is necessary that they see only their tasks in the support service, and they could not change anything and create in other projects and tasks of other people.
The second problem is sending letters to customer support. At the moment, emails are sent only to users registered in the system. Clients, already at the invitation of the support letter, are not sent. That is, when commenting on a problem or changing access only to yourself, and clients do not come.
