Spanish language Q&A Forum

Hi, I think the translation for 12 is wrong, it's not saying anything about being "key":

I'm not sure if i like this new format... not sure if it's my computer or an update on your end, but any time i select an answer (even if i try clicking outside of it), it's saying that the questions is unanswered... i don't understand why it's not accepting my answers when I am selecting them.. it's BEYOND frustrating. 

The text says:

Desde entonces, hemos sido como uña y carne

In all the lessons with desde to mean 'since' we are told to use the present tense.

I put 'Desde entonces somos como uña y carne' but was marked wrong. What is the error here?

Gracias

A useful addition to your program would be a way to study vocabulary, like flashcards or something. Any plans for that?

I answered a question with Ustedes se curan and it was marked wrong.  The correct answer was se curan without the ustedes.  I don't understand why both answers aren't correct. In the conjugation table you have the option to use or not use the pronoun.

What about using an article in front of being a stay at home parent? Soy madre. Soy padre. Is there an equivalent of this in the Spanish language?

There’s too much new material in this lesson. I was only familiar with present subjunctive. To introduce two new subjunctive tenses here is a little much. 

i am confused. there is another lesson that uses deber in perfect tense and deber in present + haber to indicate assumption that something must have happened that is expressed by the main verb as infinitive or past participle. This lesson seems to be speaking of the same thing until the last part that says 

Eso debe de haber caducado hace tiempo

In the example "A veces ________ que llevamos casados 20 años", why is simple olvido wrong? - when there was another question in another kwizz about forgetting a towel, and olvido was correct. How are we supposed to know if something is accidental or not? I must say that I find this lesson absolutely confusing and no matter what I put in the answer, it always seems to be wrong. 

(And I notice that it lists me as C1. I'm not C1, I am still struggling with B2. The Kwizbot doesn't understand the fluctuating nature of how people learn, forget, re-learn, get wrong again, and so on.)

I was marked wrong for using “habían” when the sentence was something like “habían muchos mensajes …”. If “había” is used for one thing or many things when would you use “habían”? It sounds more natural to say “habían muchos mensajes …”
