I ran into this interesting bug the other day - let’s say this is our repository:
All I wanted to do was importing the console.yml pipeline in Azure Pipelines. Well, I quickly learned that if you do not ever import the azure-pipelines.yml file first you are not going to be allowed to do that:
There is a way around this though - if you use the Classic Editor you will be able to point the import process at an existing YAML pipeline.
Nifty little bug, hopefully it will be fixed soon.
