Google Voice may use mobile data even when on Wi-Fi

Beware of this intended "feature":

There were reports even before 12/2022, but I just noticed this (what I'd call bug) the first time.

This is not about using up mobile minutes when "Use carrier only" is selected.
Rather, this is when "Prefer Wi-Fi and mobile data" is selected, and Google Voice decides to use mobile data even when on Wi-Fi.

To force Wi-Fi (and override Google Voice's selection), toggle on Airplane mode, toggle on Wi-Fi.

At the same location:

• One LG Phoenix 2 phone running Voice version 2022.12.26.499603069 did not use mobile data.
• Two LG Xpression Plus phones running Voice version 2023.04.03.521591364 used mobile data (when on Wi-Fi, and when Wi-Fi Calling was also on as indicated by icon in status bar). But did not use mobile data when moved closer to the router.

I'd say if you're you're not mobile and have good Wi-Fi signal you still should be manually switching off mobile data. That's the only way to be sure with these things. Automation isn't all it's cracked up to be.
