After the latest update (2caf5d79ba), my chat bubble and “My Thread” menu item show a unread indicator, it does this in the top bar, sidebar, and the chat modal itself.
There is no unread thread, I’ve clicked them all, and I can’t find any way remove the unread marker.
This can be different thing, but all Apple’s i-devices shows the blue dot. Androids are fine. Threads aren’t in use. Has been such that this week, upgraded three times and last time was Friday.
