Unfortunately, we don't have the answer to this. But, many users don't like the function. The more people who submit feedback the more likely the company is to implement the option. Here's how to submit feedback: 1. Open Snapchat and tap your profile icon in the upper left-hand corner. Then, tap the Settings icon just as we did above. 2. Scroll down and tap on the I Have a Suggestion option. 3. Let Snapchat know you'd like to turn off typing notifications. 4. Choose the topic that suits your needs. Then, submit your suggestion.
