ESP32-POE problems on just UEXT pins?

[KeviNH]

Has anybody seen an issue where Post in UEXT subforum? 

Specifically we are using a ESP32-POE-16MB, connecting to Serial1 (on GPI36) via the UEXT, and in a deployed device it became unreliable sporadically,then yesterday just stopped working entirely.    A multimeter shows no continuity between the board edge EXT for GPI36 and the corresponding pin on the UEXT.

Not seeing any physical reason for this fault, no unusual mechanical stress on the ESP32-POE-16MB board.
