It seems like this bug has been in the Health app for many years. When I contacted Apple support today, first AI and then a live agent described a functionality that doesn’t exist. Going into edit and tapping on a medication is supposed to bring up a Schedule section where one can change a medication’s schedule however no such section shows up.
The agent then scheduled a call back which happened right away. That agent also was reading the same script and when I asked them to try it themselves, they realized it doesn’t work. They asked me to hold but the call was dropped and there was no call back. I contacted support again and was told a call back is scheduled for 2 PM today. That call never came.
I don’t understand how a basic functionality is missing from this app and hope my reporting it will get it on their list to fix.
Will keep you posted.
