Today I was working on Dynamics 365 CE UCI online version and noticed that Advanced Find button is missing.
I am sure that we don’t have any control on those button via Custom code or configurations. Thought of raising a support ticket with Microsoft and before doing that did a quick search and came to know that someone has disabled the setting in System Settings.
I don’t even know that there is a setting for this 🙂
Advanced Settings –> Administration –> System Settings –> General Tab –> Enable embedding of certain legacy dialogs in Unified Interface browser client –> Change the setting to Yes
By default, the setting “Enable embedding of certain legacy dialogs in Unified Interface browser client” is set to Yes.
Hope this helps.
