A summary for testflight release process via fastlane, for a project which enabled bitcode, the DSYM file needs to be generated via applestore, hence there will be a asynchronous timing interval in between the uploading the archive to apple store and sync the dsym file from apple store and the crash monitoring service.

Update from 2026:

Now the DSYM files can be directly generated locally without the need to download from App Store Connect.
