does unity 5.3 android sms billing status require configuration changes ?

Hello,
- does receiving sms billing status using unity 5.3 on android requires any special configuration compared to unity 5.2 ?
- (we've checked all the release notes but can't find what's causing the issue)

DETAILS

we use a plugin that allows sms billing on android (users pay using sms), after updating to unity 5.3 it stopped working. (it worked again after reverting to unity 5.2)

• users are charged

• but they are not rewarded

• (the plugin can't detect the billing status)

NOTE:

• we've built two apk files, one using unity 5.2.0f3 and one using unity 5.3

• we've bought some stuff using unity 5.3 (sms billing)

• payment results were not caught by the plugin (players are not rewarded)

• then we deployed the 5.2 apk on the same android phone.

• it immediately received all the payment results we made with the 5.3 apk
  
  

MANIFEST FILE

The plugin uses these permissions & broadcast receivers:

uses-permission android:name="android.permission.RECEIVE_SMS" uses-permission android:name="android.permission.SEND_SMS" uses-permission android:name="android.permission.READ_PHONE_STATE"

receiver android:name="mp.MpSMSReceiver" intent-filter action android:name="android.provider.Telephony.SMS_RECEIVED" intent-filter receiver

receiver android:name="mp.unity3d.PaymentStatusReceiver" android:permission="com.your.domain.permissions.PAYMENT_BROADCAST" intent-filter action android:name="mp.info.PAYMENT_STATUS_CHANGED" intent-filter receiver

Thanks.
