Hi, I'm John! I will help you with this.
All Microsoft accounts include 5 GB of free OneDrive storage. If you recently subscribed or renewed your Microsoft 365 plan, your storage should increase to 1 TB.
Have you recently subscribed or renewed your subscription? If so, it may take about 24 to 48 hours for the updated storage quota to show across all your devices.
If the issue persists, please provide more details about the issue.
