Some people faced the same problem, I don’t really know why. Best to ask chess.com: https://support.chess.com/article/295-how-do-i-report-a-bug-or-make-a-suggestion or maybe ask a moderator for a quick answer, but I am not sure they know.
Is the Openings Stats section broken?

I put in a ticket for this issue on April 9 and was told it was referred to developers, but no updates so far.

I submitted a bug report a couple weeks ago and never heard back.
I've found I can do what I want with Lichess by looking in the opening book, selecting "Player", and then setting the time controls and date ranges I'm interested in, so I'm switching to there for now.

I also submitted a bug report for the same problem and got zero communication.
Staff is aware of the issue and have a ticket in on it. That said, Bug reports don't normally have any kind of communication unless staff is unable to reproduce the issue it needs additional details.
If someone puts in a support ticket, the support agent will reply to that ticket, though it might be just that the bug was passed to devs or that they have a ticket on it
I'm trying to look up opening stats at the URL:
https://www.chess.com/stats/openings/xaptive
or more generally
https://www.chess.com/stats/openings/<username>
It has no stats for games I've played in the last 90 days, except for 1, even though I've played 167 games . I've changed my repertoire since then and I'd like to get an idea of how I'm doing. Is this stats feature deprecated, broken, or what?
