I also have the same issue - nothing has changed about our Fastlane build process, but recent builds aren't showing up with the download dSYM link in ASC. We have started signing and uploading multiple builds for the same binary (with different build numbers for TestFlight vs. App Store release) - a previous poster mentioned something similar. Could that be the problem?
