PDF has compatibility issue

May i know how to fix this? I’m not dare to delete to note because i’m afraid that i will lose all my annotation. And even though i import the new version, the annotation is not link…

Anyone can help?


Is there any excerpt on the pdf where this issue appears? Would you mind sending this pdf to us? While waiting, you can try to send this pdf to Xodo reader and save it as a new pdf document to see if there is an improvement. Xodo's reading engine is "pdftron", which uses relatively stable technology.
