Have you ever come across a scenario, where you installed Sitecore, and load the Sitecore dashboard, but only to find out whole Experience profile dashboard is missing.
You might be wondering, may be installation gone wrong, or any configuration is missing.
Couple of months back, I had faced this issue, only later to figure out that, actual issue is my Sitecore license supports CMS only mode, not the XP (Experience Platform).
If you are facing the similar issue, always first check your Sitecore license.
If you do not have a valid xDB license, CMS-only mode is enabled by default.
Happy Troubleshooting :)
