How do you triage "doesn't work" issues — authn vs authz vs app config?

Running Auth0 across a few B2B/B2C apps and keep hitting the same pattern when a user reports “I can’t access X”:

The first 20–30 min always goes into figuring out which layer actually broke:

  • Wrong credentials / MFA issue
  • Token’s fine but missing a role or permission
  • Actually a redirect URI / SDK config issue on our side

Curious how others handle this:

  • Do you have a checklist or runbook you go through?
  • Anyone built tooling that auto-classifies the failure layer from log events?
  • Is this a real time sink for your team, or am I just slow at reading logs? :sweat_smile:

Mostly trying to figure out if this is a “get better at the logs” skill issue, or something more people hit.
