"Payment requested by abnormal app" (code 12) when network connection is restored

[Remstam]

Environment:

• OneStore Unity plugin 1.2.0 (com.onestorecorp.sdk:sdk-iap:21.01.00)
• Sandbox mode, Global store

The test scenario:

1. Launch the app, go offline (airplane mode)
2. Call PurchaseClientImpl.Initialize
3. Plugin answers with "A device or server network error has occurred." (code 2)
4. Restore network connection
5. Call PurchaseClientImpl.Initialize once again
6. Now plugin answers with "Payment requested by abnormal app." (code 12)

I have OneStore global client installed and have logged in there. If I try to launch with network connection from the start, then everything is fine, I see purchase window and can successfully proceed further (choose Fail or Success).

Here are some logs from logcat I've got (where I get code 2):

And those ones where I get code 12:
