I'm using this approach: https://stackoverflow.com/a/25796908/3437433
It works like a charm, but when I'm trying to use it in Safari (both desktop and mobile), then quite strange things happen.
On desktop, origin link https://wa.me/?text=123
is somehow replaced with whatsapp://send?text=123
. And then Safari displays error page about wrong protocol.
On mobile, correct page is opened by origin link, but also alert appears saying "can't open page because url is wrong". I can close that alert, can click on "send" button, but then https://whatsapp.com/download/
page is opened, instead of prompting to login to whatsapp and redirecting to chat.
Does anybody know what's going on here and whether it can be fixed?
