Some of my old releases are stuck to status running.
I am not sure if this affects the performance of my app somehow, if it is messing things up.
How can a newer release being done and ready and the older ones still running?
This is something that we see from time to time when a deployment is interrupted/cancelled. Occasionally, the release doesn’t get marked as failed in our backend so it still shows as “running” when it’s not. These cases are confusing but benign display issues. They shouldn’t affect future deployments or hurt your app performance.
