no xcode crash logs any more?

hello, xcode used to be good at getting crash logs from the apple servers. now we are getting crash reports from users (reported in the apple test flight console), but when we try to look for the stack traces in xcode, there is nothing there any more. any ideas why those are not getting uploaded? do we have to ask users to flip some switch on their device settings to allow upload of crash reports?

no xcode crash logs any more?
