Getting (#135000) Generic user error
Yesterday all templates suddenly stopped working, even with different numbers associated with the app. Meta returns the following response:
{ "error": { "message": "(#135000) Generic user error", "type": "OAuthException", "code": 135000, "error_data": { "messaging_product": "whatsapp", "details": "Generic user error" }, "fbtrace_id": "AvBt1NvrjsxKhrhe3GS8V1b" } }
What should I do or who can I contact to solve this issue?
