Profile - Completed Games - Explore Games.
Why are the games I've recently played not being imported to Explorer?

Yes, that opens the Explorer but then when I search the opening moves of a recent game they have not been imported.

Hmm. I searched an odd opening played by my opponent in a recent game and the Explorer displayed the message "Upgrade to premium to explore your own games." This might be the issue.

Not sure I understand what you are referring to. Are you simply wanting to examine old games? If yes, would it work to simply download your games in pgn format and sort them into folders by date? (Then use a pgn viewer like SCID to play them back later). Or is what you are talking about something totally different?
In order for our games to be imported to Explorer, chess.com says the games have to be "Standard rules that are at least 15 ply (or 29 ply if timeout) and played against a human." I have recently played blitz and daily games that match that criteria and are still not showing up when I search for them. I have even waited over 24 hours to give the system time for the games to import. I'm starting to wonder if it's because I haven't paid for a membership...
This is important for me because Explorer is a useful tool for viewing opening statistics and finding old games to learn from. I appreciate any support on this topic!
