This question is about Kakao Talk specifically, but more about share extensions in general. I just got an iPhone 6s+ having made the switch from Android. While I'm happy with the iOS 9 so far, I'm stumped at the sharing feature - in Android, if I'm browsing in chrome or whatever, I could easily share the page by hitting the "share" button - then a menu with every application popped up - including whatsapp, sms, facebook, etc - which would allow sharing of the webpage through that application. I was browsing an article in Safari and tried to share it with a friend via Kakao talk and was stumped to find that I could only share the article via only a couple of different applications - whatsapp, imessage, etc. Why isn't every application listed here? I use Kakaotalk often with my friends in Korea (it's used by 95% of people in Korea). Similar issue - I'm looking at pictures in Photos, and can't send or "share" it with instagram as it's not listed in "Actions". Instead, I have to go to Instagram, then select the picture from Photos. Am I doing something wrong or is there a way to activate Kakaotalk or Instagram share extension feature?
