TOPIC:

when i swipe through pdf page(left to right and vice versa) after creating a highlight, the same highlight gets mirrored in the previous and next page... the pdf seem to create highlights on the next page by itself. help please

We cannot replicate this with the demo project, Can you?

If not, this means it has to be something wrong in your implementation.

No, I cannot. reason being in demo project - the pdf is scroll up and down, whereas in my project is swipe left and right.

We have checked left and right swipe in the demo project (by changing the view mode to "3") and still cannot reproduce your issue.
