I had some display issues recently but just once and currently not reproducible.
For this kind of situations I’d love to have the ability to transfer a screenshot as PNG via USB to the local drive or to the app. It would also help in some other cases since the images in the app sometimes differ from the E1 display. Shooting with cameras or smartphones sometimes cannot catch every detail and mirroring lights are also tricky to avoid.
Just an idea if it is not too much effort to do.
