How to Activate visualisers on iphone & iPad?

I activated visualisers on iphone and ipad in Plex Amp but i still only see the album art. Im not seeing any visualisers. How do i activate it

Server Version#:
Player Version#:
Tuner Make/Model:
Guide/Lineup name:
Using XMLTV?:
Channel number/Name:

I also keep selecting different visualisers but i don’t see any.

Clicking on the poster on the Now Playing screen should switch between poster and visualizer.
Long-pressing the poster/visualizer lets you pick which visualizer is being used.

It’s not working, long pressing does give me the option to select on but nothing happens once i select it. Same behaviour on iphone and ipad

Tap the poster while a song is playing

I did, it doesn’t work. I have tried tapping multiple times.

Aah ok, i was casting it to my apple tv. Playing it on ipad and it works now.

They only work when playing locally, otherwise it doesn’t have access to the audio data.
