Online Store loading issues in Safari

Details:
Multiple pages on the online store are no longer displaying correctly in Safari on MacOS. Looking at a category will not show anything at all, a blank page with (Show More), but most of the UI is missing as well.

I had gotten something before about a month ago without an issue, so it's happened since the last time I've visited the site.

Using the Web Inspector when trying to initially debug it, it looks like it's missing a javascript package:
--- Begin ---
Unhandled Promise Rejection: ChunkLoadError: Loading chunk 9 failed.
(missing: https://store.finalfantasyxiv.com/st...06202102063921)
--- End ---

Operating System: MacOS 10.14.6
Browser: Safari 14.1.2

So, as I read the issue with the Steam stuff on a post above, this one was related as well due to having to clear cookies. Once that was done, the Online Store worked like normal.

I had this same issue and came here looking for an answer. Deleting the cookies fixed it for me as well.
