Sandbox: OfferAccessDeniedException after switching to business account — user 111409884 ------ [ASAP / pilne] Sandbox: OfferAccessDeniedException — konto zwykłe zamiast firma — user 111409884

There was a problem:
- [x] with a REST API resource
- [ ] with a production environment
- [x] with a test environment
- [ ] with a login or authorization
- [x] other

**Environment:** sandbox (`api.allegro.pl.allegrosandbox.pl`) via Connect Direct
**User id:** 111409884
**Login:** Client:111409884
**Endpoint:** POST /sale/product-offers

Company details were accepted by email (invoice data):
- Pattern Sandbox Sp. z o.o.
- Grunwaldzka 182, 60-166 Poznan
- NIP: 7770000005
- KRS: 0000123456

Sales configuration still shows: “Patience… Verification can take several days / waiting for confirmation from payments operators.”

GET /me still behaves as a regular account for offer APIs. POST /sale/product-offers returns:

Please verify/activate this sandbox account as a **business (konto firma)** seller so we can create offers via the Public API.

**trace-id:** (paste from the 403 response headers if you have it)
