@Mansi_ASUSHello.
I have tried in the beta section to report a similar issue with Google pay on the zenfone 9 but I had no luck getting any acknowledgement on it.
To explain the issue, whenever I tap to pay for something with nfc, Google pay opens in the work account (parallel account) and not on my phone account.
I have never used the parallel app for Google wallet because it is a part of the play services.
Can I get some attention with this issue so that I can help you find the reason for this happening?
I have tried to manually set the default payment app under settings, and it is currently set to the normal non-paralell app.
