I use two up-to-date GOS Pixels , neither of which will auto-update apps using Play Store.
- devices are on wifi explicitly selected for unmetered
- all apps have been closed (none are running idly)
- devices are plugged into power
- devices have been left to sit idly while plugged to power source and on this unmetered wifi
- Play Store is given Unrestricted battery access
Device #1 is running Play Store only in Owner Profile. Device #2 Play Store in Owner and one User.
I started using Play Store only right before the whole debacle with Aurora Store a month or so ago. During this time, Play Store apps have never auto-updated.
