[KDE Connect] Slideshow remote pointer only shows up on laptop screen

I am trying to use KDE Connect’s (1.29.0 from F-Droid) slideshow remote and specifically the pointer to control a presentation on LibreOffice in Tuxedo OS 3 (with Wayland). The clicker works fine, and I can navigate the slides fine. But the pointer only shows up on one screen (laptop) regardless of which screen is set to be the main display.

Is this a known issue that I can get it to display correctly on both screens?

Also, bonus question: I will be using this out of my own home, but I have never used KDE Connect outside of my home network before. As long as they are paired up, and I am connected to the same WiFi, my phone and laptop should still recognize each other? What do people typically do in these situations?

EDIT: Seems I was mistaken, and it is installed from Play Store via Aurora. I have upgraded to 1.32.5 now, and the issue persists.
