I hear what you’re saying, but it seems to me that a recent update might have compounded this problem. A few weeks ago, I was able to load my flex fields with only a short wait (maybe 3-4 seconds). Now, with no changes on my end, it takes over a minute to load them, if it loads at all.
(EDIT: The problem has compounded in Safari. In Chrome, it seems to work as it used to.)
