I've got a Samsung tablet, and have always had the "require authentication" for purchases, as it's mostly used by my young kids. We've never had a problem, until this month...
We went on vacation and took the tablet, in this time my son was able to rack up $1500 worth of in-app purchases in just a few days (when we noticed what was happening).
I was wondering could an auto-update of OS/Play Store have changed the setting?
My wife actually spoke to somebody at google support, and there was mention of cache being cleared? (I'm not sure, I only heard second-hand). And I haven't been able to find an update log of sorts?
It's a Samsung Galaxy Tab A(2016), Android 8.1.0 Play Store is currently, 18.4.15 (though was 18.3.13 the other day).
Like I said, it appears authentication has become disabled without our realisation around January 5, 2020. (All transaction prior to this were intentional)
Any genuine advice or suggestions are welcome.
