I've received two invitations (415286992 and 415286993) to a single job (~01f2ace4a9210de200). Please check this. If it's a bug, please don't create any support tickets on behalf of me. I don't care much, just wanted to let you know about this.
Thank you for contacting us and reporting this. We have escalated your report and our team will investigate it further. You can accept one invite and reject the other one!
