This project https://circleci.com/gh/Financial-Times/workflows/biz-ops-schema was accidentally tagged with v2.0.0 on a given commit.
I immediately went to circleci and cancelled the workflow.
I then correctly tagged the commit with v2.0.0-beta.7
On returning to circle I saw that not only had v2.0.0-beta.7 started, but v2.0.0 appeared to have restarted and completed
It’s possible that I’m mistaken as to having successfully cancelled v2.0.0, but the only way I can think to investigate would be for circleci engineers to dig into the logs
