Tooltips only appear on dashboard once

Thanks for your quick response Cherry. This is the first time that I have tried to use Tooltips, so I haven't tried it on other reports / dashboards. However, I have just created a dummy pbix file (https://arkschools-my.sharepoint.com/:u:/g/personal/s_rowland_globeacademy_org/EedCVaboAhZBqbxc1c8tDGEBMEE-U46w5-GmFy6ZR5nGAA?e=V40NMZ) which I hope that you can access and this has the same issue.

Please can you advise me what I am doing wrong? I have the following session diagnostics.

Kind regards

Steve
