Yeah confusing! But at least it is moving...That's a good question because I noticed that the VO received the file on the 14th but on ECAS it said that they started reviewing the application on the 30th. 'In process' was shown since the 12th even. It's confusing.
Maybe @nursegabo is right, it really depends on the visa office.
I guess all of us are on the waiting game now. Hope apps move faster this time.
