I see 24 hours report completely broken and unreliable in AppStoreConnect Sales & Trends for more than a month. When I submit a complain, all they say is clear cookies and caches and restart the browser. Either the complain is not forwarded to engineering or engineering is not acknowledging the issue.
So, you should file a bug report with details showing the issues.
Note: I did not experience such problem, which does not mean they do not exist but are not systematic.
The 24-hour report has been broken for me ever since the time around iOS 16 release. And it is off by about 90% for me too.
