A Microsoft file hosting and synchronization service.
Hi,
The pop-up persists because it’s likely tied to a platform bug, cached data, or a forced system element that doesn’t allow manual removal. Since it appears on both mobile and PC and lacks a block option, the issue is account-level or app-level rather than device-specific.
Quick fix steps:
Clear cache/cookies on both devices.
Sign out and back in to refresh account sync.
Update or reinstall the app/browser.
If still stuck, report the issue to the platform this is often the only way to remove elements that are hard-coded or bugged. I hope this Helps!
