EasyAR 2.3 - Black screen on iOS build on Unity 2018.3!

I'm using Unity 2018.3 with a project using EasyAR 2.3. The build on Android works fine, but a build for iOS doesn't render the camera, even though the tracking works fine. I'm using OpenGLS 2.0 API and I've filled the camera usage description on the player settings! Please help, it's very urgent! Thanks in advance :D
