What's are the uses of bonne nuit, bonne soirée, and bonsoir

Ive been marked correct for bonsoir ça va

How come when I said, "bonsoir, ça va", it marked it wrong?

I remembered that Duolingo taught me Good evening was bonne soirée. When i answered, it marked it was wrong :(

"Bonne soirée" is good evening and "Bonsoir" is good evening ? what is the difference

Thank you,

Bonne nuit is Good night

Bonne soirée is Have a good evening

Bonsoir is Good evening

Just to make sure I understood this: bonne soirée only works when there is a departure, whilst bonsoir works when there is an encounter without a departure?

Ca va is the familiar tense correct? To a strange I thought it was proper to use Comment allez-vous? the non familiar. Also I thought in asking a question, one inverted the pronoun and verb as I used above. Can anyone comment on these permutations of the language?

I tried bonne soirée and got it wrong. I seem to remember it being more of a "have fun this evening" than a casual evening greeting. Can anyone confirm?

Bonsoir, ca va ? This should be ok, too !
(of course, with the squiggle under the c)

Bonne soirée, comment ça va ? Why this is wrong??

how is this pronounced

I love this app

Is it ca va OR sa va ?

When to use bonsoir vs bonne soiree
