Why did "Simole Share" file share disapear after Marshmellow

[AC Question]

I habe Note 4. I used Sumole Share to click on a large movie, click shate & simple share was an option. It would send to someone via text. Then theyd get a link, click it, enter my (senders) ph# & the file would upload to their ph. I loved it as only way to send large files, esp in a text. My sinple share option is gone when i click "share" iv tryed sending my latge file thru the other options as email, messenger, etc and all say file to big or doesnt support format. Why did this go away! It was only way to send a large file over mobile!! Do you have to get an app for it now? Anyone with answeres, comments, greatly appreciated! Iv got screenshot of the icon if thetes a way to post here.
