Yes indeed, this is a known issue. Thank you for the quick feedback !

At the moment we are relying on table from SteemSQL that are not refreshed in real-time. A few minutes idling should be enough time for it to catch up with your latest comments.

That is one reason why we suggest (at least for now) to wait for 10 minutes before reloading. The other reason it that there might still be some pending actions to be performed.

Persistence of the queue is something which has already been solved (and will be available soon). The SteemSQL part requires some tweaking in the database queries and might take a few more days :-)
