I’m mentioning that it’s a bad idea to Only use that account for Aurora Store and microG services.
You need to log it into a few other apps on the web too. This gives the account more “livelihood”. Of course nothing you use the account for should be anything you care about; you just need to occasionally log into it through a browser and browse YouTube while pretending to be someone entirely different from yourself for a bit and check emails or compose a Google Doc, full of nonsense of course, for it.
