Builds that are successfully uploaded are not showing up in TestFlight

I've uploaded 2 builds today via Xcode. Xcode says they've been successfully uploaded.

Additionally, I've attempted to re-upload the same build multiple times, and as expected, I received an error indicating that the binary was redundant, implying that the uploads were in fact successful.

However, when I go to TestFlight on AppStoreConnect, none of the builds are showing up in the list, even after ~5 hours.

This is blocking our QA process and preventing us from doing a few sales demos this evening, hence my question.
  1. Is anyone else experiencing this?

  2. Normally this process takes ~20 minutes start to finish. Currently, I'm at 5h and nothing. Is there an expected time frame that Apple uses as a guideline - should I be more patient?

  3. Is there any magical workaround for this, short of side loading an IPA?
