Screenshot displays screenshot ok but there is no image
I am trying to take a screenshot for my channel which I have created with InstantTvChannel.com SDK mode). I have successfully uploaded and published my channel.
I would now like to update the screenshots in my app.
I go into developer mode on my Roku Box, connect to the box from my computer through the correct ip address. Once there I click Utilities then Screenshot. See attached screenshot.
It Displays Screenshot ok but there is no image. What am i doing wrong?

Screenshot Utility
The screenshot utility enables developers to capture images of sideloaded channels. These images can be uploaded with a channel submission to showcase in the Channel Store after publication.
To take a screenshot:
- sideload a channel
- Navigate to the screen that needs to be captured
- Click on the screenshot button
Screenshots will only work for sideloaded channels and static content, so screenshots of video will not work. FHD (1920x1080) screenshots also require a 4K-capable Roku set to 1080p or 4K UHD display type.
