Lazada PH - Can't use voucher for multiple stores - Vouchers disabled for 3 days

So... I used ONE free shipping voucher on two stores. Checkout was successful. 

But when I tried to checkout again, this time, using a free shipping voucher on ONE store, I received an error. Unable to connect. You account was flagged for suspicious activity and vouchers have been disabled for 3 days.

Using a voucher for multiple stores
will get you temporarily banned from using vouchers.

I will update after 3 days.
