This began after the triangle of death. Forerunner 955 no longer charges on an AC powered usb power plug. It starts charging and stops after 30 seconds or so. It will fully charge when plugged into a pc. The pc connection shows a watch full-screen radial percent charged as it progresses. All other functions are normal. On current beta software. 22.21 but I'm not sure this is a beta issue. I'm going to remove the post from the beta section.
