Hi,
I need some help or advice on the following issue. We have a coworker who is no longer with the company, so i want to remove the user account. But here i run into issues, which prevents me from removing the user.

I belief it has to do with the fact that the user created its own instance. See screenshot below "companyname-team-sy....atlassian.net". I have no access to this instance therefore i am not able to remove the user.

How to fix this.
Thanks
