[BUG] Restore purchases error validating

Description

I've had to switch back to my old phone (a now venerated Pixel XL) briefly because my Pixel 5a motherboard failed overnight.

When I click restore purchases in Sync I just get an "Error validating" toast.

Scenario (steps to reproduce)

1. Unsure....use a Pixel XL? Use Android 10?
2. Click "Restore purchases" on any screen that allows it like the setup screen, or from the settings menu.

Result(s)

"Error validating" toast
