Samsung Smart View not working error: "Can't open app"

This year, and it maybe a Samsung update that did this, but I no longer can get Smart View to screen mirror unless I go onto Hisense Roku TV and in "Advanced System Settings" I click on "Network connection reset" and then it works every time, and then  my Samsung S23 is connecting fine mirroring my phone to the Roku TV. Problem arises with this type of fix is the TV no longer has internet. I have to reset the network connection with my Roku login and password every time I use Smart View. I've done all other recommended solutions: clear caches, reboot Verizon wireless router, reboot my Samsung S23, reboot Hisense Roku TV. Made sure on Roku TV that "screen mirroring" is "prompt" and now it's on "always allow" either way works fine. Screen mirroring devices don't have anything blocked and my phone is shown on "always allowed devices". I've done software updates on everything. On my Roku the "Device connect" says "enable device connect". On Roku the "Control by mobile apps" is enabled. Anyone have an answer to use my Smart View again,  without having to always reset network connection on my Roku TV?

    Same issue here. I have tried everything. Literally stopped working a day ago. Never had a issue before. Ugh

    Ditto. Smart View from my S23 and my S7 Tab have just stop connecting to my Roku Ultra. The message I keep getting is "Can't open app" ...  'RokuCast' could not run because it could not be reinstalled for the network..."     

    It's worked for the past 2 years for me without an issue.  Now all of a sudden it stops

      Hey, slindenmuth 

      It seems you're experiencing issues using Smart View on your Samsung S23 with your Roku Ultra. Let's get more details on this. 

      • What steps have you already tried to fix the issue?
      • When did the issue first start?
      • Have you tried screencasting on the other Roku device to see if it displays the same error message?
      • Can you send a photo of the error so we can take a look?


      Looking forward to your reply!

        Hi. Thank you for reaching out. I'll answer your questions with a bulleted list in the same order of your questions. 

              *I've tried connecting to the same network although I've never had to do that before 

            *It stopped working a week or two ago 

             *I can still connect to the TCL TV with Roku built in just not to the Roku Ultra itself.

           *I've always have been able to connect to the Roku Ultra with my Samsung's Smart view

            *I'm not sure how to leave a picture here for you.  I don't see that option available.  The message is in a white box and says "Can't open app Roku - RokuCast could not be run because it could not be reinstalled from the network. Please check your network connection and try again."

        I prefer using the Roku Ultra instead of the built-in one on the TCL TV. The Roku Ultras picture comes in at a much better quality. Smart view has always worked from my phone or even from my S7 tablet and my device and Roku never had to be on the same network. That's what Screen View is all about. It has just stopped working the past week or two. I've been closed screenshots and pictures. 

        Regards,

        Steve
