My question for HN, and more specifically for IG developers on HN, is why are you disabling features?
It would be understandable if the rationale was to drive traffic to the app, but no error saying 'you must use the app to browse by hashtag' is displayed when you try browsing on a browser, you just get a page showing the top posts, with no explanation why other posts are there. So that reason doesn't cut it.
Same here. I think it's to stop spam. Very annoying though.
