Hello @Cezary Klus - Welcome to Microsoft Q&A and thanks for reaching out.
Since we haven't heard back from you, we are hoping that the issue is resolved for you.
I have also tried to reproduce the issue but was unable to do it and I have also confirmed the same with our internal product team here and confirmed that there are no existing issues going on with Azure Managed Application deployments.
Hope this helps. and please feel free to reach out if you have any further questions.
