We're using a pdf library called Sync Fusion to automate some fillable fields in a pdf but after the text has been placed it is not visible due to the form field high-lighting.
So far we have tried the 3 things below but nothing has solved this issue.
Anyone have any other ideas that might fix this? We're going to try a different pdf library next.
Trying a different library is the correct option since this behavior only happens if the PDF filling process is invalid (aka doesn't follow the rules in the PDF standard) by not including an "appearance stream" for each field after filling.
