Hello there, nick-harris,
Let's try to do basic troubleshooting to check if this is a browser-related issue. Use a private browser, this disables saving the browsing history and the web cache.
- Google Chrome: press CTRL + Shift + N
- Mozilla Firefox: press CTRL + Shift + P
- Internet Explorer: press CTRL + Shift + P
- Safari: press Command + Shift + N
If it works with a private browser, please access your account with the default browser and clear cache. The browser hold onto information which can cause problems over time. It's always a good idea to clear cache on regular basis. Or we can try to use a different browser.

I appreciate your patience on this. Please let me know if I can provide any other additional support.
