'Find' Facility in Microsoft Edge

Hi I hope anyone can help.  Since my computer installed Microsoft Edge I have lost the facility to use 'find' on a pdf document.  Some documents I have to read are 100's of pages long and I really want the 'find' facility.  Is it there?  Is it coming back?  Also 'read aloud'.  Why has it gone. Please bring both of these back.  

If anyone knows that they are there and I am missing something please let me know!  

Thank you.
