Honestly I’ve done mostly forgot, and with the proliferation of AI technologies and all the typos AI has read from in the training models, I bet AI isn’t always right about this either.
I usually just don’t care anymore, whether the autocorrect puts the apostrophe in or not.
Others are telling you you’re an idiot but you’re not.
The noun-pronoun distinction for the possessive apostrophe is irrational. Unlike other European languages, English never had a formal institution to dictate orthography. This odd incoherence would never have lingered in French, let alone ultra-logical German.
Personally I think the possessive apostrophe looks semi-illiterate even when it’s correct. It should be Harrys Bar like it would be in German.
