Possible to join the ATV beta?

Just purchased a HDHomerun Quattro and discovered Channels....love to mess about with new things and help to test too having done so for lots of other products.

Wondering if there is a way to join a beta for Channels TV app for the ATV (4K if it makes a difference)

Either way, enjoying browsing through the forums and looking forward to getting involved


After a further scan of the site...it looks like the beta is now only open to those paying for the DVR service....I will keep looking into this and see if its something I want to do...thanks anyway
