Since last week a new user was created in our Jira called "Aha! Product Roadmaps". It seems to be a user created by an addon to to some interactions.
1. We haven't installed this addon!
2. We cannot work with Jira anymore because our lincensig pool is exhausted.
Unfortunately I cannot delete or deactivate the user because the system gave him automatically admin rights.
How could this happen and how can we solve this?
