I got the approval today, exactly 30 days after I applied, and I received it at 1206AM spanish time, suggesting the approval was set to automatically approve on that date. Maybe it's to extend the validity (not vaste from the 5 years before you travel).
I applied there on Aug 12, they asked the next day for another document, then after that nothing. I emailed them two days ago to ask how long it will take. They replied and asked when I'm traveling. I replied end of September, they replied and said that then the visa should be approved soon.
