Well, it is very hard to say whether it was a known issue or a very specific problem in your case.
However, we can try one more approach. Please try to reproduce this on the current latest stable release of Grafana OSS and see if there it is reproducible. You can simply create a v.basic VM running Grafana and replicate your steps to reproduce it.
The same thing happened to me. I’m going to have to stop using short links because of this. Which is fine because short links always say they’re copied into my clipboard when they’re not (on Safari / macOS)
The issue persists. It’s a great idea, as it allows the ability to share a specific log message. But since they expire, they are useless. Our team has had to reconduct investigations because of this issue. Would be great if Grafana would increase the retention period…
