Gradle Build Error: The attribute application@allowBackups=false in :audioinaec: collides with another value

I have a VR application with networking I am currently working on. Everything was building and working fine in my project. I then imported Photon and Photon Voice and now it will not build for me throwing the above error.

The only manifest I have in my project is that of the AndroidManifest.OVRSubmission.xml:

  <?xml version="1.0" encoding="utf-8" standalone="no"?>
 <manifest xmlns:android="http://schemas.android.com/apk/res/android"
     xmlns:tools="http://schemas.android.com/tools"
     android:installLocation="auto">
     <application
         android:label="@string/app_name"
         android:icon="@mipmap/app_icon"
         tools:replace="android:allowBackup">
         <activity
             android:theme="@android:style/Theme.Black.NoTitleBar.Fullscreen"
             android:configChanges="locale|fontScale|keyboard|keyboardHidden|mcc|mnc|navigation|orientation|screenLayout|screenSize|smallestScreenSize|touchscreen|uiMode"
             android:launchMode="singleTask"
             android:name="com.unity3d.player.UnityPlayerActivity"
             android:excludeFromRecents="true">
             <intent-filter>
                 <action android:name="android.intent.action.MAIN"/>
                 <category android:name="android.intent.category.LAUNCHER"/>
             </intent-filter>
         </activity>
         <meta-data android:name="unityplayer.SkipPermissionsDialog" android:value="false" />
         <meta-data android:name="com.samsung.android.vr.application.mode" android:value="vr_only"/>
     </application>
 </manifest>

I've tried adding the tools schemas and android:allowbackup as some users had suggested but that has not helped whatsoever. I've also tried deleting the Library folder and allow Unity to reimport but that did not help either.

Any help is appreciated!
