You have to phone call to the Embassy between 15:00-17:00. It seems they are going to hang up, but wait, and press 102 for the extension. You will find a lady that she will clarify your doubts, be patient with her, at the end she is really nice
The matter is that my husband started the proceed before me for the OA visa.
Since I am not yet 50 years old, I am 48 years old, we were not very sure which visa I had to apply for. It seems that the spouse of those who have an OA visa only can apply for an O visa, which is "single entry" and therefore did not suit our needs. So I applied for the DTV visa, something we were not very sure what the outcome would be. The fact is that my husband is now "pending approval" with his OA visa!
