Doorbell 2 - Not staying charged with Plug-in Adapter

Hi all, I have a doorbell 2 that is plugged in using the OEM plug in adapter:[https://shop.ring.com/collections/accessories/products/plug-in-adapter](https://shop.ring.com/collections/accessories/products/plug-in-adapter)Device shows hardwired, but it still loses about 5-7% charge a day.I am getting upwards of 24VA out from the adapter.I get minimal motion and virtually no doorbell action.I've shortened the wire coming from the transformer as I've read elsewhere that that has helped some people, but I had no change in results.Any suggestions?Thanks in advance!
