The users access CRM trough the browser in the iPad and would like to do an advanced find.
The advanced find is not available.

This is an Expected behavior as the pop ups don’t work well on the iPad. 

It is on the roadmap to convert advanced find to the modern UI, but with no timeline defined.

Workaround is to create system views that address customers’ needs and use the filters on each column to select specific data based on certain criteria.
