> Note: The use of nonplussed to mean "unimpressed" is an Americanism that has become increasingly common in recent decades and now appears frequently in published writing. It apparently arose from confusion over the meaning of nonplussed in ambiguous contexts, and it continues to be widely regarded as an error.
I actively try to avoid USAmericanisms, except for "y'all". Go figure ;o)
[That last phrase is a USAmericanism, used for amusing intent.]
Rough synonyms: confounded, flummoxed, bewildered, perplexed, stunned, shocked, dumbfounded, flabbergasted, thunderstruck.
Using nonplussed to mean “unimpressed” or “apathetic” will leave listeners both unimpressed and confused.

My observation: "continues to be regarded as an error" is a bit of a "that's not how linguistics work" thing
