Not working: Charge optimization - limit to 80%

[mrpackerguy]

This feature in the Battery>Battery Health>charge optimization>limit to 80% setting doesn't work. My 8 pro continues to charge to 100%. A reddit poster gave a fix to leave the charger on all night and in many, not all instances, it does seem to reset it to the 80% charge limit, but within a couple weeks, it's back to charging to 100% despite not changing the setting and when viewing the setting, still seeing it set to 80%.
