It is completely unusable.
I'd love to use it but I get nothing but error messages.
Here's my latest issue- I created two tabs with a data visualizer then saved it- all fine. Two issues: -
1) Next day I open a new tab in the same workbook, open a hybrid organizational chart and get 'Sorry, we couldn't create the diagram with the inserted table'. Repeatedly.
2) I now cannot even edit the original tabs, I get 'An unexpected error occurred, click "reload" and try again". Repeatedly.

Hello Jo, Could you please reach out to us at "tellvisio [@] microsoft.com". Would like to understand more on the issues you are facing and investigate. If there is not personal/confidential/sensitive etc. information in the file, would be great if you share the file as well.
I cannot use this wonderfully advertised feature. I am signed into the correct account and have a Office 365 subscription. Totally disappointed.
