After updating Safari to version 15.0 (16612.1.29.41.4, 16612), App Store Connect refuses to load "Sales & Trends". Other tabs like "My Apps" are loaded properly and Firefox has no issues showing my trends, but Safari is just presenting a blank page (titlebar only, no navigation, no charts).
Apple, what a shame that Safari cannot render even your own web sites...

I filed a bug report and it seems to be corrected now in the last version of Safari Technology Preview, but not in this version of Safari.
A workaround.
The URL is:
https://appstoreconnect.apple.com/trends/insights?pageid=8
remove the end to keep only:
https://appstoreconnect.apple.com/trends/
Ignore the error message
We're Sorry. We can't find the page you're looking for. Please click on a link in the left sidebar.
And click on Units or Sales. You'll get the usual page. But overview will not work.
You should file a bug report.
Here is the reference of bug report I filed for Safari Technology Preview: Sep 15, 2021 at 7:16 PM – FB9627832
You can mention it in your bug report.
Use Firefox 92.0.1. It just works.
