How do I process a GooglePlay payment if I don't get a response from Google?

Question

Android

Hello!
Often, when paying, users do not receive a response from Google with payment data, although the payment goes through, i.e. Google application does not give data: token, purchase ID, etc.
Accordingly, there is no way to check whether the user paid or not. This happens somehow in waves for several people at once, for the most part, payment goes through for everyone. Waiting for a response over the network costs the maximum.
What could be the problem? Maybe someone knows what to do in this case?

Maybe someone knows what to do in this case?

do not close the transaction, and periodically ping Google about unclosed transactions.
