Droid Cam not working

[Fulminare]

Hello

I am using two phones as a webcam using droid cam
One phone is working fine.

On connecting the second phone, the camera is showing on the droidcam app display but not in OBS

Both the phones are connected using USB
I would be much obliged if anyone can kindly guide me

Regards.

[Update]

It started to work once I forced stopped the app on the phone.
