Sunday, April 30 about 8 AM Ohio-time the Free Preview channels for May showed up on my Hopper. I programmed some shows for the coming week that I wanted to check out. Monday, May 1 I double-checked which channels were on Free Preview on the Dish Network website to see if I'd overlooked any I'd be interested in. The May Free Previews included RFD-TV, Cowgirl Channel and a few others than I can't remember now. Today I noticed that all my scheduled recordings of Free Preview channels were gone from the Hopper Schedule. I double-checked that "All Subscribed" was my Guide choice but none of the Free Preview channels are there now. I've just checked the Dish website and they no longer show any Free Previews page for May. Their home page banner just has 2 entries "May On Dish" and "May DISH scapes" now. What happened?
