Here is the sentence I am struggling with:
"DataFriend is our software that maximizes your efficiency."
My gut says this is wrong. If the sentence said the software or a software or just software, I'd be on board. But using "that" as a relative pronoun when the noun we're defining is preceded by a possessive determiner... feels wrong.
The thing is, I don't know why it feels wrong.
Is there a grammar mistake here?
