Heart Rate Data and External Coros Arm Band Monitor

Latest Firmware update to Garmin 255 has rendered Coros arm band HR Monitor useless. I deleted the device, re - paried to my Android phone . Device shows as connected to my 255 when I start a run , but no heart data is communicated to the watch. Separate issue, but using wrist based HR monitor on the 255 seems more inaccurate than ever. , showing insanely high heart rates at very low intensity, I have tried shutting the watch down, re-sterting, heart rates still way too high for the effort exerted.

Yes, so until there is the stable release we will not know about, beta firmwares are unstable firmwares and this is the real mission of it
