Okay my happiness was short lived 
Today OSMC decided to get upgraded and once it got upgraded Tubecast no longer seems to work correctly. Every time I go to programs and click on Tubecast, it starts pairing process with YouTube also it is no longer seen on official YouTube app for casting
I’ve uninstalled both Youtube as well as well as Tubecast add ons including deleting settings. Reinstalled YouTube and Tubecast but this made no difference.
Further I’ve noticed that my iPhone 5s with updated Youtube app still connects, this was the device I used in the first place, however my Android phone with Youtube does not see the RP/Tubecast. I disconnected the 5s and tried the Android but still no effect. With the 5s now even though I can connect, playing any video crashes the RP and I see the frowning face icon on a blue screen.
