I disagree that they want us to migrate to business accounts. If so, I think that they would have made that option available and clear. I have heard people with business accounts are having the same issues.
See my other post in regard to this issue and the Microsoft team's reply.
"We fully understand the inconvenience and disruption caused by this issue. Our team is actively addressing it and working hard to fix it as soon as possible. By June 1^st^, 2024, our community support has posted the bug reports on the feedback platform for internal use. We are committed to resolving this swiftly.
I understand that your usage scenario involves family members using it for both personal and business purposes. Regarding your question, I would like to clarify that the current situation with OneDrive is not determined by your subscription type (Personal, Family, or Business), so switching to the Business plan may not directly address the issue you are experiencing.
OneDrive, as part of a Microsoft 365 subscription, is designed to provide users with file storage and synchronisation across devices. The quality of service and functionality of OneDrive is the same whether you are a personal user, a member of a family plan, or a business user. If you are experiencing any other issues with OneDrive, this may be due to issues with the service itself, or it may be related to your device, network environment, account settings, and other factors."
