We recently added Inventory Write permissions to the app (approved about two weeks ago).
However ANY write request to Inventory results in 401. This affects new clients (installed the app AFTER permission approval) and existing clients (reinstalled the app). We verified that new tokens are being obtained, and even instructed some clients to wait 24 hours to re-install. Verified on re-install on both native and OAUTH.
App ID : 3CQA074T95S6R
Happy to provide active tokens to resolve.
