I believe there is a bug using the address:/// syntax
I have been trying to figure this out all evening. I did find the third slash would make it open. The problem I was having is if you open the link
[Bill Gates](addressbook:///DAEBFBA7-5D8A-48C1-91D6-607063EBF969:ABPerson)
Then try to open other contact links i.e.
[Melinda Gates](addressbook:///BDDAHJP9-6F7B-62C4-99F8-706630FBE696:ABPerson)
The contact link using the address:/// syntax Contacts does not switch to the proper persons contact information? It will open Bill Gates. It appears to get stuck on the first location and does not work on additional links?
I did find using a .hook file for the contact then copying the Biil Gates.hook as a MD link which uses the syntax file:/// syntax with a path to the hook file works and opens the correct contact information. Extra step but at least it works consistently from my test so far. Any thoughts on this? Thx
