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.
I hate that my phone turns “its” into “it’s” seemingly every single time. I often forget (I don’t post from my phone very often) and often only notice later and have to edit a post. It’s maddening.
