Thanks Lynn.
I am using APM 10.1 version.
I tried reducing the image size and also tried different file types (.PNG, .JPEG)
Still the issue persisted.
A restart of the MOM was performed as part of a different activity, after which the dashboard is displaying correctly in webview as well.
Is there a way to identify if there's any web caching problems or capacity related issues associated with webview?
Regards,
Leo
