Norton Password Manager UNUSABLE on T-Mobile Branded OnePlus 6T

Thanks for trying, but with all due respect, "end of life" is no more than a trite expression in my opinion.  This phone isn't "dead," it has merely been "poisoned."  It's far from dead, its heartbeat is FUERTE.  Rather, my feeling is that someone who wants me to buy a NUEVO device is slowly pushing out "OnePlus 6T arsenic smoothies"...and I think that stinks.  So, not that I'll get a straight answer from a T-Mobile Developer; but I will wait (hope?) for a straight answer from someone with intimate knowledge concerning those two files I mentioned.

By the way, I should add that this issue doesn't impact only Norton Password Manager on my device.  It also impacted LG ThinQ y ResMed’s MyAir--GRATIS apps (not ones I have to pay for, so there's no incentive to "break" them)--and possibly others I don't yet know about.  Both of those apps also "broke" with a similar "This app doesn’t work on a rooted device” message.  But why?  My device has never been rooted!  Certainly not with my knowledge.

No, this is just like dominoes falling or the proverbial straw on a camel's back...every new "push" makes previous devices less and less reliable.  And while this might not actually be "planned obsolescence," to me, something is rotten in the City of Bellevue.
