I heard some have used Wise personal or business account which maybe a problem? Otherwise not sure what else? Which type of option in the DTV did you choose, remote worker, freelancer, one of the soft options cooking class etc?
I doubt they will respond. There are standard checks they do on everyone, do you have any form of previous arrest, criminal record, previous over stays etc I don't know but they will turn you down if that's the case but only you know this. Of course it vould be something else, which bank did you use for proof of funds?
