We recently upgraded from Enterprise 11.1 to 11.3. Everything is working fine now, however, many of our end users reported issues with Experience Builder apps. Those on the GIS Team also had issues in Portal (maps wouldn't save, the Portal site was still styled as if it was 11.1 rather than 11.3, etc.). The only solution so far seems to be clearing the cache and cookies related to our Enterprise site so it seems like the users were stuck on the old version of Enterprise. We have noticed this sort of behaviour in the past with other upgrades of Enterprise.
Do others experience this same problem? If so, is there a better solution than having our end users clear their cache/cookies? Many of them are not tech savvy, so this presents a significant hurdle when trying to roll out an Enterprise upgrade.
Ok, thanks George.
@CameronMcKee1 Incredibly useful question - I read through this, holding my breath, waiting for the answer. Alas, there isn't one! Lol. Did you ever figure this out?
I'm sorry to disappoint you, but I do not have a solution at this time. I have an enhancement request with ESRI (ENH-000171651), but I do not know when (or if) it will get implemented.
I should also add a link to this idea: Invalidate Cache/Cookies After Enterprise Upgrade - Esri Community.
Wonderful, thank you!
