Enterprise-grade edge stuck in "Enabling" for 48+ hours — blocked by phantom "disablement in progress" error (extendedCode 59355)

**Static Web App:** ProdPortaalPD
**Resource group:** ProductiePortaalBZK
**Subscription ID:** 66e28812-4643-4467-9517-682ed963327b

**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.

No repository file or test is named. Start with the reported `az staticwebapp enterprise-edge enable --name ProdPortaalPD --resource-group ProductiePortaalBZK` reproduction and inspect the resulting `enterpriseGradeCdnStatus` and extended code 59355; done means establishing whether the platform can clear the stuck operation or documenting the required platform-side guidance.
