Mark read on new posts sometimes doesn't.

[doppler]

Under new posts. The big button to mark all new post as read. Followed by the OK. Some times does not do it. Next day on new posts I get the follow posts have not changed. Which means yesterday the mark as read did not happen.

FTR: I did not uncheck on the confirmation pop up.

Does not occur with regularity. Or repeatable. FYI.
