Hi, I’m in Samsung s10 and I have downloaded Nebula lastest version. When I’m in the app with my glasses pluged on, the both app option are greyd (MR Space and Air casting). Impossible to make that work ! I’ve tried to restard several times and plug and unplug the glasses. The glasses are reconize by Android, it showing the mirroiring of my screen phone but won’t work with Nebula.
Thanks for help.
