I'm using the link https://image.ibb.co/nMJhN5/Alexa_carlogo_512x512.png for the image for my cards. In the app and online, it shows up as a gray box with the words "no image found," but on the alexa show and the alexa show render in the service tester, the image shows up fine.
The image was also working for the cards yesterday. Any help is appreciated. Thanks
