Hi @LaurenBoyd and @John-Foster ,
I've been having similar issues to @FarrukhZahid as far as using API keys. The documentation you linked was the first time I seen that note, because all of the docs I've been going through kept mentioning that you get api key auth if you're using enterprise server 11.4. Since the Maps SDK, at least per that obscure note that I wouldn't have looked for in the Arcgis Portal section of the Maps sdk, doesn't allow auth via api keys yet, does that include Experience Builder as well?
I was hoping this was the fix for my portal sharing problem where I have secure services built in the portal, and when I try to access popups publicly, it asks for a login.
Sorry if that sounds curt, I've been going rounds with these auth issues for awhile.
Thanks in advance!
