   Type: Incident Duration: 9 hours and 26 minutes Affected Components: Content Sync API, Web application & API, Website Sep 11, 20:06:17 GMT+0 - Identified - Our developers discovered that the issue was caused by a change we implemented yesterday. We are currently reverting that change to resolve the problem. Sep 11, 19:13:25 GMT+0 - Investigating - We have identified a syncing issue in shared projects where changes (like adding or completing tasks) do not sync immediately to other collaborators' accounts. These changes only sync after performing a LOLI (Log Out and Log In) or after a long wait. As a result, notifications for task assignments and completions are also not functioning properly, which may cause delays in collaboration. Our team is currently investigating this issue. Sep 11, 20:09:46 GMT+0 - Monitoring - We are currently monitoring the result after reverting the change. Sep 12, 04:39:01 GMT+0 - Resolved - We're back 🚀 The sync issue has been resolved. We sincerely apologize for the turbulence! 🙏 If you are still experiencing issues with Todoist, please submit a ticket via our [contact form](https://todoist.com/contact).
