I'm the same POU27,  my undelivered invoices are lighting up like a Christmas tree, I've no idea if they are getting through to our clients and overdue invoices are increasing daily.

I just don't know what we do apart from vote on our feet and move to another provider, shame as the rest of platform is great for us, I'm just fed up with being ignored now and seems posting on here Is just pointless as they don't care about their customers.
