One of the questions on the B2 quiz asks for several options to translate the phrase "After I've read the report I will give you my opinion." The only two correct answers it lists are "Después de que haya leido el informe te daré mi opinión" and "Después de que haber leido el informe...". I understand why both answers are correct, but I wonder why "Después de que he leido el informe..." isn't, since it's also indicative and both the indicative and subjunctive can be used for past tense?
Thanks!
