Something has been wrong with Explorer for quite a while. Not only is it not updating your games, but with games that are uploaded and you want to view games with similar positions (by either clicking on the "View all games from current position" link underneath the list of next moves, or by clicking on the number beside the next move, Explorer will just display your recent games, regardless whether they have the same position or not.
I thought more people used Explorer and there would be lots of complaints about this, but apparently not, and it does not seem to be a priority for chess.com, assuming it is even aware of the problem.
I recently started playing a3 against the Sicilian and I wanted to see the most common responses but they aren't being found in explorer (despite the fact that I've already played it many times).
Here are 2 recent examples:

What am I missing?
