    Have been encountering this all day long. Trying to upload build to google play, got this error. Quick google search revealed forum post that said, that GPBL v5.1.0 is added in latest IAP package. Updated it to no result. Since there are only forum posts about v4, and all of them contained answer like "update IAP", came to conclusion to start asking around

    Having the same problem. I'm using Unity 2021.3.14f1 and IAP 4.9.2.

    I get the message on Google play console as:

    We've detected that this app is using an old version of Google Play Billing. By 1 November 2023, all app updates must use Billing Library version 5 or newer. Update to Billing Library 5 before this date.

    But Unity documentation claims to support Google Play Billing v.5.1.0 in IAP v4.9.2

    Can't find any posts relating to Google Play Billing Library v.5

    Strangely the error is gone after pushing couple of updates.
