I damaged the antenna connection on my Roku 55R6AX model and purchased a Sling AirTv2 device so I can watch local channels. None of my efforts have been successful as this TV will not allow screen mirroring . I first tried with my pixel phone and found roku doesn't play nice with Google devices.I next tried either my Samsung Galaxy TabA8.
Have followed all pertinent instructions from each of the devices and believe the problem lies with the Roku tv and mynot being able to add the tablet to the allowed devices list. I did check the always allowed choice to no avail. Please help me to avoid a repair bill with quotes greater than the cost of a new tv

Re: Cannot add device to screen mirror on my Roku TV
I followed all the instructions to connect my Insignia Roku TV to my laptop as extended desktop on Win11. The remote device mode is on prompt and my laptop does not show up as allowable device, but the account name for the email is there.
When I try to connect the wireless device, it pops up the purple screen with the devices trying to connect, then comes up a screen that says "Starting video streaming from..." for 3-4 sec (with a button to stop video, tried that too) and then the whole thing goes away and I return to Home screen.
I am trying to extend (or even mirror) my desktop to the TV. BTW the pop-up to choose whether to mirror or extended the desktop does show up on the laptop.
I tried everything I could thing of. It seems that they do recognize each other but somehow are refusing to connect for my desktop to display on the TV. Is there something I missed?
Thanks

Re: Cannot add device to screen mirror on my Roku TV
Thanks for sharing this issue with us.
To mirror your screen to the TV, just ensure both your device and Roku are on the same Wi-Fi. Next, head over to Settings > System > Screen Mirroring on your Roku and choose Prompt or Always Allow.
For detailed information, you can also visit our support article on how to screen mirror from your phone, tablet, or computer to your Roku streaming device.
Let us know how it goes.
