We're working on an issue where any network connection issues that occur when Tracker checks in, may cause Tracker to stop syncing. When this happens you will see a persistent spinner on any stories you try to make changes to. Although you'll be able to continue to update your project, it will no longer be saving anything you do. If you see a persistent spinner on any stories you've updated, please leave the browser tab open, open a new Tracker tab, and copy any changes you've made into that new tab.
We apologize for any inconvenience this causes, and we anticipate releasing a fix ASAP. Please email us at firstname.lastname@example.org
if you have any questions in the meantime, and we will respond as soon as we can. Thank you for your understanding.
