Sticky Notes Account Login and Sync Issue Report

I have a habit of using sticky notes as a daily memo tool, and everything has been functioning normally until recently.

On the morning of Friday, November 29th, I suddenly discovered that my sticky notes were unable to sync. After testing by logging out and logging back in, I encountered the message: "Your account does not have an email address, so your sticky notes cannot be saved to the cloud." Since then, I have been unable to log in.

That day, I contacted Microsoft Support. An engineer conducted remote testing and found that it was not a system issue, as other accounts could log in successfully. However, the account I normally use, email address removed for privacy reasons, could not log in to Sticky Notes. They advised me to contact customer service and get assistance from the account department.

The next day, on Saturday, I contacted the account department. They asked me to log in to Microsoft using my regular account, which I was able to do without issue. However, I still could not log in to Sticky Notes, leaving the account department uncertain about the cause of the problem. They then transferred me to the Office department, but they were also unable to resolve the issue.
