A Microsoft file hosting and synchronization service.
Hi, I'm John! I will help you with this.
Could you check how much storage is shown when you sign in to OneDrive web https://onedrive.live.com?
Also, where did you purchase the additional 200 GB storage? Was it purchased through Microsoft, your mobile provider, or another service?
Sometimes newly purchased storage does not appear across all Microsoft services right away. It can take 24 to 48 hours for the updated storage allocation to sync everywhere.
