**Description** I have followed the steps for activating the JWT authentication for the API, but apparently every request I make is invalid due to an invalid token. I have tried using the JWT provided on the app page, but with no success. After browsing the forums, I have seen that this may be a caching problem, but I have waited a day and it has not been resolved. **Error** { ``` "code": 124, "message": "Invalid access token." ``` } **Which App Type (OAuth / Chatbot / JWT / Webhook)?** JWT **Which Endpoint/s?** All of them **Screenshots (If applicable)** ![JWT](https://us1.discourse-cdn.com/flex016/uploads/zoomdeveloper/original/2X/4/498bd3a612379c3dd74b89994c0648aee9d5e031.png) ---
