It is a smooth app, great for photo and video sharing. However, it has become overrun with bots, spam and scam accounts, which instagram seem to be doing nothing about. Also videos auto play, which is irritating when they're below the post you're actually looking at (this is only true with adverts, which makes it clear why they play). Over the last year this app has really become frustrating; bad advertising practice and terrible issue with bots. Reporting bots and comments is useless.
