We're setting up review apps with GitHub integration.
We followed this: https://help.heroku.com/R8AE3YBV/why-did-my-pipeline-disappear#:~:text=If%20you%20do%20not%20have,the%20pipeline%20is%20automatically%20deleted.
and created a default dummy app for our review app pipeline.
It works fine in the first couple of builds and review apps...
Then the pipeline keeps disappearing from our dashboard :( (seems deleted).
Why and how to fix that?
