Cleaning up a bit - this was moved to a solution and resolved there. Caching issue.

Can't mark my answers as solved now either even though the cache is cleared. I think I'll stick to chrome from now on... 🙂

Likely a simple caching issue with the browser. (while still not a root cause - calling this one delivered for now)

Cheers.

No worries Patrik_Jonsson - browser caches are, maybe, the bane of any web-app's (administrative) existence. Knowing about another symptom of a bad cache is good info.

Thanks.

Worked after clearing the cache for F5.com. Sorry for wasting your time!

Trying to edit this comment. 

Changed back to Investigating. (interesting I changed it back by commenting in the wrong place)

I tested under your account, on Safari (Version 15.5 (17613.2.7.1.8), on a comment on this question.

Looks like it worked ok.

I went as far as to click EDIT on a comment on BIGIP Report article and it looked like I could have saved the edit - I chose not to.

So - I can't confirm the behavior.
I confirmed our vendor supports these browsers on Mac - no known updates indicating otherwise for any latest versions.

Thanks Patrik - I'll take a look.
