App window mirroring display is stuck


I hope somebody can help me with this.

I have a playlist in OBS with different scenes (pics and videos).
I want to stream the scenes via Manycam.
I select desktop/App window as source
Manycam displays the first scene but stuck (if it’s a video it doesn’t play)
When I change the scene on OBS the display doesn’t update on Manycam

Basically the display from OBS is not reflected on Manycam. Manycam just shows the first thing that was displaying when I started sharing and doesn’t update the content displayed on OBS.

I’m using Windows 10.

Thanks in advance!
