Pdf comments - Sticky notes freeze file
INDD 18.0 PDF comments has something chronically slow going on with the sticky notes. We have done some testing here and also confirmed by other in the forums https://community.adobe.com/t5/indesign-discussions/pdf-comments-sticky-notes-makes-document-extremly-slow/m-p/13368359#M503963
If you delete the sticky notes the file will work as expected. But if you have 1 sticky note on a page, any editing on that page is painfully slow!
WORKAROUND - action sticky notes outside of INDD then delete them and import the file. Not ideal but manageable until Adobe can fix this one.
