What are the size limitations for custom images for the App Invite API? They don't appear to be documented.
I am convinced (by trial and error) there is a size limit enforced by the API. It does not throw an exception. The invite activity simply does not display the image preview (which I find reasonable).
Some general recommendations on what size/orientation will look good with the default email would be helpful. I know there is a custom HTML option, but I'm interested in using the default.
Note: If you specify a custom image, use a square image that's around 600x600 pixels and no larger than 4000x4000 pixels.
