Why am I asked to log in to Google to update the app?

The Play Store requires a Google account active on the device.

If you don’t have a Google account you’ll have to obtain the APK from a mirror service and sideload it. But I assume you’d know this if that’s how you got the app originally without a Google account. How did you install the app originally?

I don’t have a google account on my Android phone, so use yalp to install play store apps without an account.
