Same here, we have been experiencing about the same time as you have been. Yes, we are using App Store Connect API to upload our binaries. We are using the App Store Connect API for our normal release with the option " Automatically release this version" and that works fine without any issues. For our next release, we will not use the App Store Connect API to upload our binary and see if this works (I see you mentioned that it worked for you) I think this narrows down the issue when using the option "Automatically release this version after App Review, no earlier than" and using the App Store Connect API to upload the binary is clearly not working. I have opened a case with Apple and they suggested contacting them when we're ready thus they can try reproducing such issue from their end.
