If there’s one thing that has changed the most this year have been the updates to the Instagram inbox. First came the "Vanish Mode" option which allows you to send messages "secretly" without having to save the chat history, and then came the famous stickers, which you can use for any kind of situation. Finally, Instagram brings the next change, again related to DM: Quick Answers!
If you are not yet familiar with the term, "Quick Replies" are abbreviated texts that allow you to respond quickly to messages that come to you in the inbox, but more than personal conversations, such an option will help businesses. It will shorten the response time and give you the opportunity to be clearer.
For example, instead of writing at length to explain details about their business in DM, quick ready answers will help them be more precise.
You can not use such an option in a personal account, but you can create them through a professional profile. How can you do that?
In your profile, click the "Settings" option. There you will find another option, “Switch to Professional Account. By activating this you can start returning quick replies to DM.
Another way to access it is from your inbox. While writing a message, you will see an icon added to the right of the chat, next to the option of photos and stickers. Click and send the first lightning answer!
