We have released a fix that should improve the experience for many users. There were reports that despite being logged in on the top navigation, the comments section indicated that you were logged out. That should no longer be occurring.
At this time we will continue investigating the other reports, including timeouts and authentication errors, and try to alleviate those as well.
Please reach out to us at firstname.lastname@example.org
if you continue to have additional issues with being logged in, staying logged in, or want to make us aware of another confusing account issue you are experiencing. Thank you!
