This is my third and final attempt at getting a custom nRF52 board to appear on my phone as an Adafruit Feather device. I have no issue with the genuine Adafruit hardware so I though I would make a custom version with onboard sensors. I've installed, upgraded the bootloader and made leds blink to verify that my custom board works but the device never appears in the Bluefruit Connect app. It is very likely that the antenna layout is not ideal but I was hoping this third revision would appear on the list with the phone close by. Below is a screenshot, schematic and attached are the gerber files. I'm at my wits end and defeated.
