Notice, that notifications are not sent for events, where the assignee is the same as the user making changes. Therefore, if you are testing Notiji by making changes to your own issues, no notifications are sent.
While our business hours are Mon-Fri 9:00 AM - 5:00 PM GMT+2 with a target response time under 24h, we usually respond to support requests in a few hours and outside business hours too, if available. So please feel free to contact us anytime.
