Hi everyone! Thank you to all who shared feedback on this and submitted reports of this being an issue. I wanted to confirm that our developers are aware that this is a problem some of our merchants are facing and are actively working towards a resolution.
As many of you have most likely done already as a work around, you should be able to use an alternative browser or you can also make the safari browser window narrow so that there is a horizontal scrolling bar when viewing admin pages with columns and rows (customers, orders, products).
I’ll update this thread once I can confirm that this issue has been resolved.
