@AndreyPavlenko could you check if this is a secrets permission problem in the pipeline? Seems like because I was the one who triggered it, secrets are unaccessible

[AndreyPavlenko]

Please rebase on the last commit. It should skip this step if secrets are unavailable.
You can probably configure your own secrets in your fork. Then you'll get apks signed by your certificate.

Should be done now
