Platform Application tokens returning 403 across entire account

All API tokens from our Platform Application started returning 403 Forbidden today around 1:11 PM EST. Tested with:

Multiple freshly provisioned tokens from the same app
A brand new platform application with a fresh token
Both curl and Python requests
The API is reachable via browser session (returns data fine). Only programmatic access via Platform Application tokens is blocked.

Endpoint tested: GET https://vetrinex.myclickfunnels.com/api/v2/workspaces/111375/orders

Is there an account-level restriction on Platform Application API access? Has anything changed on your end today?
