Maximum possible dimensions are 1,038 pixels x 1,038 pixels
Images that are taller than 1,038 pixels will be downscaled with padding to give them a square appearance
In other words, you can use an image up to 1,038 pixels wide x (any smaller number)
- We recommend using images that have a landscape orientation. Although a portrait orientation will work, it could make the push notification tall and awkward looking
Keep images between 800 and 1,038 pixels wide
Maintain a landscape perspective, as rich push notifications on Android are cropped to something close to 16:9 (the exact ratio changes depending on the device)
