Just a heads up, when I contacted Google Support about this, they insinuated that this is something slowly being rolled out across Pixel 5 devices, so while it may work now, it could stop at any moment.
The issue I received when tapping to pay was "Your phone doesn't meet software standards". It did mention it can be due to rooting (my phone wasn't rooted) or "uncertified software" (of which I didn't have any).
I'm sure you might already do so, but I'd advise not to rely on the phone to pay going forward. For me, I was caught off guard in a shop without any other payment method. There was no warning or notification about the change until I tapped to pay at the card terminal.
I tried a few more times afterwards with another payment method as backup, and it never worked again, even after rebooting, toggling NFC off and on. I never received an email, notification or warning in the app itself. It was quite disappointing as I reckon I could have run that phone for a few more years as a minimal phone.
Google did offer me about £100 off of a new Pixel. So if this happens to you and the lack of Google Pay is a dealbreaker, I'd give that a try.
Terrifying. I opened this thread to leave the same comment that Google pay is working for me on my pixel 5. I bought it second handed and replaced battery so I didn't spend too much money on it, but it would be a real shame when that rollout reaches me. Especially because I also quite enjoy the size and functionality. It's enough for everything I need to do on a phone..
In hindsight, I really miss using the Pixel 5 and semi-wish that I'd kept using it and just switched Google Pay/Wallet for card. The form factor and size was perfect.
I changed to a Pixel 9 because I had an opportunity around the same time to get it cheaper, and thought I may as well go to the latest model to keep security updates up to 2030. Even after a few months, I can't get used to the weight, size, the back case design (slippery glass and fingerprint magnet), and sticking out camera block. I still use the phone minimally, but now I carry around a brick everyday.
Yeah, I'll hold on to it until I lose the pay as well. I was looking at either pixel 8a or 9a for my next phone. Like you said with pixel 9, I assume it would be a big leap with both of these phones. But at least with 9a I won't have the camera bump problem so that's hopeful.
