Same here. Checked my Roku for software update, it was up to date. Removed the Newsmax app, searched, found the same one, reinstalled it, got one step further, instead of blue screen going to grey, it actually had the options menu on the left side but nothing but endless circle when trying to load live tv.
Either Newsmax was not ready for prime time or someone (liberal minded techy) at Roku does not like Newsmax and is messing with their programming or possibly a combo of both. I really think Newsmax should extend their free trial from 15 days to 30 days "after" the issues are resolved.
