Thank you. That is correct. Mistakenly someone has set screen limits on.
Please ask Plast or Runsgiri to remove Screen limits for you. They need to do this.
Navigate to https://family.microsoft.com and login with your Microsoft account.
Click on Screen time under your Child’s account.
Click on the slot for which you want to remove the screen time.
Click on Remove to remove the screen time.
After removing the time, click on Save and check if that helps.
