I purchased Mate 20 from official retailer (Harvey Norman) and NEVER rooted or unlocked the bootloader. Google Pay works just fine when buying things (i.e., using credit card added to Google Pay).
Recently, the public transport system allows people to use their phone as a ticket (by adding the ticket in Google Pay app). However, my device did not pass the security verification. The app prompted that the device was rooted or the bootloader was unlocked (see photo attached).
Anyone living in Melbourne has the same issue? Any suggestion?

I can confirm this also happened to other people in Melbourne.
I reported via Huawei chat. They escalated the case, I got a phonecall and talked with staff.
This morning, I got a firmware update prompted on my phone (last update I received was in March). So I tried it again. And the problem was fixed. I am so happy now.
Thanks guys for your support.
