How to like an Instagram DM is one of the commonly requested queries on your website. In reality, doing so is simple and was doable before the update. You can follow these instructions to find out how to like a message on Instagram: 1. Log in to Instagram by opening the app. 2. Click the symbol in your feed's top right corner to access your DM mailbox. 3. Decide on dialogue and a message you wish to like. 4. Double-tap the message one last time. Simple as that! However, you can tap and hold the message if you want to like it on Instagram with an emoji other than a heart. Then, select whatever emoji you prefer to use!
