Fenix 6 Pro HeartRate Sensor Non Functional / Buttons Non Responsive / Screens Freeze

After less than 1 year with the Fenix 6 Pro I have noticed that the hear rate sensor intermittently works. The optical sensor will not turn on. The buttons are non responsive even after cleaning. The menu screens have lag and sometime freeze. Has anyone else seen these issues? The watch is useless in this form and clearly a quality/reliability defect from the MFG.
