The URL schema for Here WeGo on iOS and Android changed with version 4. It's no longer here-location://, here-route://, and here-place://.
I looked at the metadata and can see it's now just wego:// for everything, but that's all I can get from the metadata. From trial and error it looks like wego://route causes the app to launch as if I had passed it a route, however everything I've tried (e.g. wego://route/mylocation/37.870090,-122.268150) results in it just sitting there with my current location as the start and destination. Similar behavior for location and place.
It looks like the old documentation for the URL schema was removed from the developer portal, and either wasn't replaced with updated docs, or has been moved to somewhere hard to find.
Can someone from the Here team please post the updated schema information? Thanks!!
