What happened to the Yahoo Finance Live channel 171

I, and I'm sure, many other people have the same question. Several times I've researched the issue and have yet to find an answer. A solution, abet, a temporary one, is to add "Haystack" to your channel lineup. I discovered that option this morning. I fail to understand why ROKU makes changes without broadcasting a notice to people that use their service. A good example is the loss of "channel number" a while back -- which has not been restored but were missing for a week or better. Come on ROKU how about thinking ahead and if something is beyond your control, at least broadcast a notice of what is taking place. Is that asking too?
