"Jag betalar med mina föräldrars kreditkort."

Translation: I am paying with my parents' credit card.

I put "I pay with my parents' credit card" and it said "Almost correct! I pay with my parents credit card" but that is clearly wrong as it lacks the apostrophe.

Yeah, JimNolt reported the same above. I think it's Duolingo acting up rather than an error in the lesson inputs. Have seen the same for other sentences, and in other courses as well.

[Arnauti]

True, there's a global problem with apostrophes. It's been reported and only Duo staff can fix it.

[DuncanHill0]

Thanks. Sometimes it marks me correct but then offers an alternative translation that is identical to that which I gave, which I assume is also some kind of internal glitch.

[Sandi_e]

Still happening

[devalanteriel]

Yup. We average well over 500 error reports per months about it, across various sentences, and there's absolutely zero we can do about it. :( It's been reported internally - repeatedly - and there does not appear to be a solution in sight.

As long as English-speakers aren't testing their English grammar, I imagine this is more of a problem for Swedes learning English with the same sentences.

[EleanorWoodward]

It did not include parent's as an option, instead parents. So it was wrong although the correct work was not included in the word bank

[devalanteriel]

There is a bug with the plural apostrophe, which unfortunately affects all sentences using them.
