search no longer working

Are there any experts/developers actually on here? I have found a current workaround - I have to open OneNote2016 (which I had to stop using because it crashes every time I try to write a note in it), select every image in the ppt or pdf file individually, and choose the right-click option to allow text search. This option then somehow syncs with OneNote365 and I am able to search there. Why doesn't it just exist in 365?!? And why did everything I added to 365 since like December (when 2016 started crashing), along with everything I added via 2016 since August, automatically allow this until about a month ago!? Whether I print it to OneNote, or do an insert file to either 2016 or 365, doesn't make a difference - search is disallowed unless I do this manual step. This is ridiculous, guys! Please fix!
