Unable to Cast to Roku TV

RokuNimfa-C,  Unfortunately, you have really not given mkatoma any helpful advice at all. I'm not trying to be rude at all, just realistic, but you basically just repeated back to mkatoma what s/he already said s/he can't do. Both of mkatoma's Roku TV and smart Android phone devices ARE already sharing the same Wi-Fi connection as mkatoma already stated. You came back telling her she has to have both connected to the same Wi-Fi when she plainly, already said they are both connected to the same WiFi. It's like you didn't really even read her issue, yet simply copied and pasted something you've read in a Roku manual. I'm commenting on this issue because I'm having the exact same problem as mkatoma and so many professed Roku-knowledgeable reps over the web are offering the same type of advice, but not really addressing the issue with legitimate help because y'all are just repeating back what the end-user says they've already done and double checked. SO! What are the specific workaround steps to get an Android smartphone to cast to the Bluetooth-compatible Roku TV when both devices ARE running off the same Wi-Fi network? The only streaming app on my Android smartphone that finds my Roku and casts without issue is YouTube (just like mkatoma): How to make all other streaming apps copy what YouTube can do when it comes to casting? Why can YouTube cast from my Android smartphone to my Bluetooth-compatible Roku TV, yet no other streaming apps can? If one streaming app on my Android smartphone can find my Roku TV and cast to it, then there HAS to be a way to enable all other streaming apps (that have the cast icon) to work properly. Can anyone please assist with this very specific issue? Otherwise, never mind...it's getting way too frustrating hearing a "friendly" echo that brings no support. Cheers! ‌‌‌‌  

I am able to cast from the YouTube app on my mobile device but not Netflix.

Is there a way to cast from my mobile device to my Roku tv using Androids screen cast feature or if I'm in a mobile app for which an equivalent app is unavailable on Roku tv? I've been able to do these functions on my Android TV.
