I figured it out after a good night's sleep.
The UI doesn't let you send a request with empty allowed instances, it either sends an array with your picks or no array at all if you selected none. To reset allowed instances you need to send an empty array to the API.
The easiest way to do it is
- Open browser devtools network tab or equivalent
- Send a request with at least one allowed instance
- Edit the request JSON body to empty the array
- Resend the request
I think Chrome lets you copy the request with authentication to send with something like curl, I used Firefox which lets you edit and resend directly.
Peace โ
