Play mode ARCamera not working in Vuforia

I am using Unity 2017.3.0p4 (64-bit) and Vuforia 7.0.47, and I am having trouble debugging an Android game with AR. The thing is, that when I build the game and test it on the phone it works perfectly, but when using Unity Remote 5 on my phone, the game is unable to obtain any image from the camera: the image background received is all black. Has anyone encountered this problem before, and if so, knows any way to sort it out?

I tried only enabling OpenGL 2.0, and Unity Remote works nicely on other projects that don’t use AR.

Thanks!

Vuforia does not support Unity remote device camera
