I use Remote Play regularly (bed-bound lots due to medical issues) and never had a problem, but have found it’s finicky on your setup. Eg it never really worked on my ISP-provided modem/router but once I got a UDM (for unrelated reasons) it worked flawlessly and has ever since.
The fact I can lie in bed with laptop plugged into bedroom TV and use a PS4 controller to play games running on my gaming PC in another room is truly awesome.
