I use com.android.billingclient:billing:4.0.0 on my application and purchases_flutter 3.10.0 for the revenuecat subscriptions.

From May 2022, users can't see the free trial or intro price options. Then, I messaged the GooglePlay and they replied as below:

Hello Google Play Developer, Due to a bug in our system, since May 3, 2022, you may be experiencing incorrect or missing subscription information in the results from the Google Play Billing library’s deprecated querySkuDetailsAsync() function. During this time the Google Play Billing library may not have returned information to your apps about free trial and intro price offers for one or more of your subscriptions, even if the user was eligible for these offers. In these cases, users only saw the subscription base plan in the purchase cart, without any free trials or intro prices.
Action Required
We recommend that you review all of your subscriptions with free trial and intro price offers in the Play Console, and ensure that the correct offers are active and marked as backward compatible. You can learn more about backwards compatibility here.
If your app uses the queryProductDetailsAsync() function instead, this is not impacted and you do not need to take any action.

Then, I wanted to try migrate blling library from 4.0.0 to 5.0.0. However, after the migration, I got the following error and app crashed.

E/AndroidRuntime( 4198): java.lang.NoSuchMethodError: No virtual method queryPurchases(Ljava/lang/String;)Lcom/android/billingclient/api/Purchase$PurchasesResult; in class Lcom/android/billingclient/api/BillingClient; or its super classes (declaration of 'com.android.billingclient.api.BillingClient'

Could anyone help with the solution?

@FlickGames I agree with you, and BillingClient 5.0 support is our #1 item in the pipeline right now. I definitely feel your pain here, especially since you built your own plugin for observer mode support.

There are a few factors in the way that BC5 is designed that have made implementing support for it rather difficult on our side, and we’re currently working through the issues to have something ready as soon as we possibly can. This year’s update was essentially a full redesign in BillingClient, with some choices that put barriers around revenue tracking that weren’t there in BC4. Not trying to make excuses here, just being transparent about the reasons we don’t have support out yet.

We aim to have a version out as soon as humanly possible, but I can’t guarantee that we’ll have it out before Nov 1st.

Is there any news on an ETA for billing v5 support since the last post a month ago?
We use an SDK which uses a billing plugin created by a 3rd party, and they have just updated it to support billing v5.
This means that we will not be able to use RevenueCat at all in our next update, so we’re eager to know when it is likely to be supported again.

Hey @FlickGames,

Unfortunately we can’t provide a specific target on the full implementation yet. However, it’s likely there will be an intermediary state where we can ship the SDK with billing v5 as the dependency version without full support of the new features. The team will have to discuss any potential side effects and risks of releasing in such a way -- I’ll post back here when we are done with that. If we can do such a release, it should be within a few weeks.
