Apple lightning to 30-pin adapter not working after 5s iOS 7.0.4

Is anyone else having problems using the Apple-made lighting to 30-pin adapter cable (not the one-piece adapter plug) with their iPhone 5S on 7.0.4? Specifically, I am seeing that the adapter is no longer recognized by the iPhone. My adapter was working fine for 3 months until suddenly last week after a 7.0.4 upgrade it stopped charging the iPhone but still allowed audio out through the adapter. I made sure my iPhone jack wasn't the problem by ensuring the USB-to-lightning cable charged normally which it did. I took the adapter to the Apple store yesterday and they replaced it under warranty no questions asked. The new one, however, shows the "accessory not recognized" message on my iPhone 5S. I took this new one to the Apple Store today and the same thing happened with a brand-new one off the shelf. Their store "tech guy" was actually able to replicate the same problem on their own iPhone 5S in the back with the brand-new adapter off the shelf. They were at a loss and suggested I wait to see if Apple has a fix. Anyone else having this problem or know if this is a known issue? Until it gets fixed, I can't use the adapter.
