Please add possibility to sync activities uploaded to the Apple Health app from a third party sources. It can be not automatic, at least make it possible in manual mode from “manage apps and devices” page.
I use Footpath app on Apple Watch for my hikes because it provides much better outdoor navigation than Apple workout app an I want to have an option for convenient sync it to Strava without exporting/importing file. Other apps like Komoot and Relive have no issues with read and import this activities.
