I received my new Harmony Elite yesterday and had everything set up and basically working. A notification told me it needed a software update so I returned it to the stand, but since then I cannot see any channel numbers whilst in the Watch TV activity. I can swipe to the page where they should be (123 in the header) and all I see is a 12 box grid where each box is empty. Tapping where the numbers should be does nothing. Any thoughts?
