my money was also put on hold since may 14th. I opened a support request and they responded very quickly
ticket number is 26112
they put it on hold for the money came from a german bank account and they explained they had information on illegal things going on with certain german bank accounts. On the other hand I'm using that bank account for quite some time now without problems and they agreed that chances are small that my bank account was used for identity theft but until now the money stayed on hold.
I mean it would have been okay for me if they just rejected to add the fund to the account and let me send it back to my bank account but no. Money is gone until further notice.
