Hi there,
We have a customer who reported that they can't view/edit/create tickets in our service desk portal as shown below.
I'm looking at a ticket now where his name is included in the "Shared with" list of customers of an open ticket so he should be seeing at least that.

Checked his access in the project->customers and still showing active with 5 closed requests.

When I click on his name though, it's showing as user does not exist so a bit confused.

Checked his access in the Settings -> User Management -> JIRA Service Management -> Portal Only Customers and his account is also active:

Hopefully someone can help me. Thank you in advance.
