Channel images cached

Hello,

I have changed the images for the channel logo, slashscreen, etc... but they appear to be cached somehow/somewhere.

I have tried removing the channel and re-adding it, rebooted the device, etc... but the old images are still appearing.

This is for a channel that has not yet been published and I am previewing it on the Roku device using the 'Device Preview' feature.

Any ideas on how to resolve/clear cache before hitting the 'Publish' button?

Thanks.
