ZapparEmbed AR functionality disappeared when compiling Android App with targetSdkVersion 30

We are updating our Android App which includes the ZapparEmbed SDK. During the update we needed to set targetSdkVersion to 30, because of the requirements from google to upload the app to the play store. Unfortunately opening the ZapparEmbed activity shows only the camera without the AR functionality (e.g scanning of zappar marks are not possible anymore). Is this a known issue and are there any solutions to solve it?
