Hashtag instagram: A Telstra ID is the only sign-in

A Telstra ID is the only sign-in you need to access and manage all your Telstra apps and services and is quick and easy to create. You can set one up within the app. But when you use hashtags in your post, Instagram splits the first 10% of your audience into 50-50, so 50% from Home and 50% from hashtags, and based on their response, the content is pushed further. I need to know when someone uses a particular hashtag so I can catalogue these posts and reply/engage with them, not just a summary of the most popular posts using it! I don't mind using an app or anything, I just need a way around Instagram 's random changes. Instagram hashtag search results only display the 9 "Top Posts," rather than the ALL POSTS that it should be displaying, so you can browse for the subjects you are interested in.
