Delete old versions of backup without running a new backup

Although the reports of this are few, here’s a theory from 2021. Can you test this?

Dev tools is probably on your browser menu, and commonly available with the F12 key.
A dismiss (in my test on Edge) looks like this. You want to get 200 for success. Do you?

If the 503 is still there, you can look at a notifications line to see how many you have.

Are you getting a lot per job run, or do they just build up over many runs without dismiss?

I doubt it, at least when I deleted all the versions of the job (and the job), the popups remained even on browser refresh. Mine was an error, but I have no reason to think warning is different.
