Store links in WeChat, LINE and Viber
If your audience is in Asia, these three matter more than Instagram, and they are stricter.

The most restrictive environment of any app in this discussion. WeChat renders links in its own browser and blocks most attempts to leave it, including schemes that work elsewhere. Even ordinary external links are often gated behind an interstitial.
In practice, publishers targeting WeChat use a QR code or a Mini Program rather than fighting the browser. A store link posted directly is unlikely to work reliably.
LINE
LINE opens links in an in-app browser with a menu that includes opening externally. It marks its user agent, so detection works:
if (/\bLine\//i.test(navigator.userAgent)) { … }Behaviour is closer to Instagram than to WeChat: the escape sequence is worth attempting, and the manual fallback is a realistic second option because the menu is discoverable.
Viber
Viber's browser is comparatively permissive and often hands links to the system browser. Store links frequently work without intervention, though the behaviour varies by version and platform.
What to do differently for these markets
- Lead with QR codes where the audience is physically present, since they bypass every browser
- Test on real devices in the target market, because regional builds differ
- Expect the manual fallback to carry more weight than in Western markets
- For WeChat specifically, plan around a Mini Program rather than around links
