I contacted support and they don't want to help because I'm not using a Mac and using a third party framework (Tauri), even though it's just using xcrun, Apple's tool...
Also I've been unable to even use the notarization API to retrieve the submission logs and Apple didn't help for that either so far (they just disregarded my ticket).
I feel powerless and abused. This is the worst DX/CX I've had in years.
As a side note, authenticating against the notarization API is a nightmare. You get a PKCS8 that you have to use to create/sign a JWT and you're basically on your own... I had to build a little node program just to craft the JWT...
