I've seen payments being another problem - but Garmin watch handles it for me. And paying with a watch becomes a conversation starter with merchants for some reason.
However Wallet didn't like this setup. Tokens expired at varying delays, sometimes a day, sometimes a week or payment failed without reasons.
Nowadays, I just use my bank's app which work fine on GOS.
I was actually very surprised Garmin supported the country I'm in. They don't even support the language script, I get squiggles, but payments - better than Google Wallet.
