Firefox / Chrome can't sync the presentation w/ speaker view

[bonnebulle]

Am following the Advanced instructions https://github.com/OleVik/grav-plugin-presentation/blob/master/ADVANCED.md

sync: 'poll' or sync: 'browser' Open my presentation : /presentation ( presentation view ) /presentation?admin=true ( speaker view )

I try with Firefox and Chrome opening speaker view into an new window ...

But, when I change slides from speaker view, the slides into presentation view dont changes... I will retry later

Thanks for all Reveal is very helpful
