In the recent weeks, we seem to not any longer reliably receive a copy of invoices we send, although we make sure that we select/click the box “CC me” in the “send invoice” menu (we seem to receive some, but not every single time we follow the process).
I have had a look and there appeared to be a temporary block against your email account, this can happen if there has been a bounce back or if you have an out of office set up.
I have removed the block so you should get the emails through ok now
