Failing to assign myself a ticket

Hello @beryl , Thank you for granting me access to jira/wiki, but when I try to assign myself a ticket, I get this error

yet I successfully logged into jira/wiki using this account.([email protected]). Kindly, what could be the problem?

@dkayiwa kindly do you have an idea of how to go past the above error? I have tried to assign @wgeorge the ticket but still his name is not reflected when I click inside the assignee input. I have also tried to invite him to jira but I have no permission.

@jwnasambu can you check again?

Thanks for your help its working as expected.
