When I first switch to a single feed, it starts to render the page with new content in bold. If I quickly hit mark-as-read (now in the upper right) it seems to update the view immediately and mark the articles as read and the mark-as-read button disappears. But a lot of the time if I do this while the article list is still rendering it seems to lose the REST call to the server and the sidebar count is never updated and a refresh brings the old articles back as unread.
One thing to fix is that the articles probably shouldn’t be marked as unread in the view and the button shouldn’t be hidden until the response comes back from the server. Then, issuing the request while its working on rendering the article list seems to cause it to get lost quite a bit…
Just replicated this with space.com (https://www.newsblur.com/site/10488/s…), and I don’t see anything useful in the javascript console…
Not a huge deal since I can probably just be a bit more patient…
