Launch the Instagram app on your mobile device and make sure you're logged into your account.
Tap on the profile icon located at the bottom right corner of the screen to access your profile.
Tap on the three horizontal lines (menu icon) in the top right corner and select 'Settings' at the bottom.
In the Settings menu, tap on 'Your Activity'.
Once you're in the 'Your Activity' section, tap on 'Time Spent'.
Here, you'll see the options for managing your time on Instagram. Tap on 'Set daily reminder'.
If you have already set a time limit, it will show up here. Simply turn off this option or set the daily limit to 'Off' to remove the time restriction.
After following these steps, the daily time limit on Instagram will be turned off, allowing you to use the app without restrictions. Note that keeping track of your social media usage is still a good idea even without the time limit.
