Help with Screen mirroring

I need help. I have a Roku Express+ and I'm trying to screen mirroring on my Samsung galaxy a02s phone but I'm keep getting the same error message 'RokuCast' could not be run because it could not be reinstalled from the network. Please check your network connection and try again. I don't have wifi in the home only thing I have is the data & Hotspot on my phone it was working lastmonth when I use it without any problems. I already updated the Roku and Factory reset still showing the samething.

Software version 11.0.0

Build 4193

I am also facing same issue. Unable to cast videos using  TV cast Roku app. 

I had been facing this issue and no one helps.

Re: RokuCast stopped working on Westinghouse TV

I have emailed them several times.  They keep telling me they are working on it then I never hear from them again.  It's been probably 4+ months since I first emailed them.  I can't figure out why it's taking this long for them to come up with an answer.  Very frustrating.  I used to be able to cast to my TV with no problems from my laptop.  I haven't changed laptops or TVs so they must have changed or updated something with the app.

Hi everyone,

Thanks for the posts.

We would be more than happy to look further into the issue, but will need more information. Can you please provide us the following information:
-Roku device model, serial number, device ID, and software OS/version (these can all be found in Settings > System > About)
-mobile device brand, model, and OS
-does this issue occur on a specific channel? if so, what channel and what version/build is the channel (this can be found be selecting the channel on the Home screen and pressing the * button)
-tracker ID when this issue occurs (when you see this issue occur, press the Home button 5 times, followed by the Back button 5 times and provide us with this ID)
-steps to reproduce the issue you are seeing 

Once we have more information, we will be able to investigate the issue further.
