Answer 1

Universal Links unfortunately don't work everywhere. From this page:

• Messages | works
• Mail | works
• Whatsapp | works
• Slack | works, if it's set to open Safari, not in-app browser (uses SFSafariViewController)
• Safari | works conditionally
• Chrome | works conditionally
• Google | works conditionally
• Gmail | if Chrome installed, opens link in Chrome (not Universal Link). Else, works conditionally
• Inbox | if Chrome installed, opens link in Chrome (not Universal Link). Else, works.
• Twitter | works conditionally
• Facebook | works conditionally
• FB Messenger | works conditionally
• WeChat | works conditionally
• Pinterest | not working
• Telegram | not working (uses SFSafariViewController)

Note: Conditionally working means that it works (i.e., opens the app) some of the time:

• Universal Links will not work if you paste the link into the browser URL field.
• Universal Links work with a user driven <a href="..."> element click across domains. Example: if there is a Universal Link on google.com pointing to bnc.lt, it will open the app.
• Universal Links will not work with a user driven <a href="..."> element click on the same domain. Example: if there is a Universal Link on google.com pointing to a different Universal Link on google.com, it will not open the app.
• Universal Links cannot be triggered via Javascript (in window.onload or via a .click() call on an <a> element), unless it is part of a user action.
• Google, Gmail, Inbox, Twitter, Facebook, FB Messenger, WeChat -- Universal Links only work when you have a webview already open. In other words, they do not work in-app from the feed / main views. Again, they also must be cross-domain, aka if your user is on yourapp.com and clicks a Universal Link also for yourapp.com, it will not work. However, clicking from yourapp.com to bnc.lt will trigger the link to function as a Universal Link and open your app directly.
