"As per the issue description mentioned above, you are facing issue when trying to edit files in Acrobat, is that correct?" Yes this is correct.
Toggling recognise text on and off does influence what I am able to edit, so thank you for that. However there is still not the same editing capability as there is in our version of XI. There are less individual entities to edit, they seem to be in larger groups resulting in difficulty in editing smaller items.
Editing capability for a pdf file depends upon how the pdf was created in the first place. If its a scanned file you are working with, you may try improving ocr results and check if that helps: improve OCR results
