Battery health missing
Hi everyone, today I updated my MacBook Pro 15" (2017) from Mojave to macOS Catalina10.15.6 but the Battery health option is missing from System Preferences (as shown in the attached screenshot). I've searched for this issue but it only seems to occur when the computer doesn't qualify for the feature - which, correct me if I'm wrong, I'm pretty sure mine does, since its 4 ports are all Thunderbolt 3. Any help? Thanks in advance :)
