Cannot create or restore content on local

I’m seeing strange behaviour on an Umbraco Cloud v17 project

Locally, I am unable to create content as the three dots and the plus next to Content are not showing

I am also unable to restore content from Cloud using the big green button…

It goes to the content section with the following URL and displays a grey overlay with the UI disabled…

There’s no way of triggering a restore from the ‘Deploy’ tab in the settings section.

I’m not seeing any errors in the console or in the logs. I feel like I might be missing something obvious, but not sure what it is

It was the browser!

Restarting Safari fixed the first issue, the … + missing from the Content menu.

Switching to Chrome fixed the second issue. It appears the modal in the back office does not show in Safari at all.
