It's nice to see you in the Community, @ewanbcn.
I'd like to help share information about the MTD page.
At this time, we received some reports from other users regarding the same issue. This is being investigated now by our Product Team. I'd suggest reaching out to our Online Support so they can add you to the list of affected users and sign you up to receive email updates as soon as they become available. To chat outside of our business hours, you can send an email from our support page via this link: https://quickbooks.intuit.com/uk/contact/.
Please bear with us while we continue working to get this fixed as soon as possible.
If you have other concerns or questions about home page errors, do let me know. I'll always be around to help. I hope you enjoy your weekend.
