Issue

Enabling "Enterprise-grade edge" (Azure Front Door integration) on our
production Static Web App has been stuck for 48+ hours.

Timeline (from Activity Log):

• Multiple enable attempts between 2026-09-02 and 2026-09-03 failed with
  HTTP 400:

  Cannot enable enterprise grade CDN on static web app ProdPortaalPD
  because the disablement operation of an enterprise grade CDN is in
  progress for this site. (extendedCode: 59355)

• No disablement was ever intentionally triggered by us — this appears
  to be a stuck/phantom operation on the platform side.

• Since then, multiple team members have repeatedly clicked "Enable"
  in the Azure Portal over the past 48+ hours (last attempt observed
  2026-09-08, ~09:30 UTC via az staticwebapp enterprise-edge enable),
  each still returning {"enterpriseGradeCdnStatus": "Enabling"}
  without ever progressing to "Enabled". We suspect repeated concurrent
  enable attempts from multiple users may be compounding the stuck
  state rather than helping — we've now stopped retrying and are
  waiting for platform-side guidance.

• We saw the exact same symptom (stuck provisioning, no forward
  progress) on our acceptance environment (TestPortaalTotaal) about a
  week earlier — that one self-resolved after roughly 2 days with no
  action from our side, but we don't understand the root cause and
  can't force-clear it.

Repro

az staticwebapp enterprise-edge enable --name ProdPortaalPD --resource-group ProductiePortaalBZK

Returns success but status never leaves "Enabling".

Ask

• Is there a way to force-clear a stuck enable/disable operation for
  Enterprise-grade edge from our side?
• Is this a known platform issue? We don't have a support plan that
  allows opening a technical support ticket, so filing here as the
  next-best channel.

Any pointers appreciated — this is blocking a production environment.
