Hi, Laurie78. Being able to quickly copy and paste details is such a helpful feature, so I completely understand wanting it to work smoothly when managing your customer information. Let me help get things back on track.
In certain cases, this issue can happen due to cached data stored in your browser, which might temporarily impact how features function. To troubleshoot, I recommend logging out of your account and then logging back in using a private browsing window. Doing this will help reset your browser session for a smoother experience.
If you’re using Chrome, press Ctrl+Shift+N (or Command+Shift+N for Mac) to open incognito mode, then log in and edit your customer information again.
This should resolve the issue and have everything working as expected. Feel free to drop a reply in the comment section if there’s more you'd like to discuss. I’d be happy to assist you further and hear how things turn out.
