From my poor understanding of how Amazon Shopping works:
Affects Fire tablets with OTA lockdown per FTB protocol.
Now opening Amazon Shopping, getting "Amazon shopping is no longer supported on this device" flag with redirect to Amazon website.
Flag triggered by Amazon for Tablets app installed from GPS. Not sure how that got installed but it appears to be that a recent app update either Amazon Shopping and/or Amazon for Tablets were updated.
Apparently both apps are related and passoff data internally. (This where I am fuzzy!)
On tablets with OTA-ON no harm; both apps updated in synch.
On tablets with OTA-OFF Shopping for Tablets updated but Amazon Shopping did not; out of synch triggering flag.
@blaacksheep thinks that GPS updated Shopping for Tablets by an accidently open Auto update app.
@blaacksheep took deep dive into app but Amazon didn't leave enough "bread crumbs" to allow rollback. He has no immediate solution.
Am I making any sense? ... still confused on deep tech of apps.
In any event, I think more tablets with locked down FireOS will be affected.
@dcooterfrog got Amazon Shopping again by a factory reset!
