Plexamp used to work on my old Pixel phone, but will not see my server on my Samsung phone. I also installed Plexamp on my laptop to see if that would work. I regularly use my laptop to watch my movies on my server, but Plexamp can’t see my server either. I am able to use plex on my phone and my laptop, but not plexamp.
I saw the help page for if plexamp can’t see my server and attempted to find the settings listed in the article on my Linksys router, with no luck.
