Hey guys, I haven't been able to get any support from the community so I'm reaching out here. I am getting an error on fetching long live access tokens. I don't have this issue with testers. I am both business and tech provider verified. Endpoint error: ```Status: 400 Error: {"error":{"message":"Unsupported request - method type: get","type":"THApiException","code":100,"fbtrace_id":"AmRXEj0Vy4vTk0rmakGMs3M"}}``` Please help.
