While attempting to upload my app to TestFlight (which has already been uploaded numerous times, including just a few days ago with the same code base) there is this error
"TMS-90338: Non-public API usage - The app references non-public selectors in : _isKeyDown, _modifiedInput, _modifierFlags....."
Nothing new there, that's been happening for months for myself and countless others and has been reported numerous times, i.e.

But now there's a difference - in the past the builds always appeared in Testflight after getting this warning, so it wasn't an issue.
But now that's changed, the build is no longer appearing in Testflight, so it suddenly is a very big issue.
