Build notifications arrive days after build is complete

We have a release build workflow for our primary app, and we set up email and webhook notifications for it. This is to hopefully not miss when this workflow completes.

Unfortunately, we seem to be getting these build notifications days after completion. This has happened several times.

In this case, the build completed Friday afternoon for us, we submitted the new version, and it was released hours later. But we didn't get the workflow notification until Sunday.

We get them in Slack and Email.

I'm considering turning these notifications off since their late arrival is rendering them almost useless.
