New apps and updates on Google Play must use Billing Library version 4

[ryffer]

Hello,
When I'm trying to start rollout of new version of my app after uploading apk, I get this error:
'We've detected this app uses an unsupported version of Play billing. Please upgrade to Billing Library version 4 or newer to publish this app.'. So there's no way to update or upload a new app with Billing Library version 3 now.
The current version of ANE is using Billing Library version 3.
I would appreciate if there's new version of ANE with support of Billing Library version 4 is coming.
Thanks a lot!

Thanks to @mateo-kozomara this Ane supports Billing Library 5.2

If you update and get same error from Google Play check the app description and update billing version like this:

<meta-data android:name="com.google.android.play.billingclient.version" android:value="5.2.0" />

I have tried to upload bundle with declared 5.2.0 version, but Google Play Console return me Error: minimum 5.2.1 version; and Warning: 6.0.1 to allow all features of Google Play. So, I think you should update up to 6.0.1, please!
