Adobe Premier Pro problems-Drawing feature can allow people to ruin my docs, even with PW protection

11/12/2025 - I have Adobe Premiere Pro.  All of my PDFs HAD a black background and were fine. Suddenly, a drawing feature appeared at the top that now allows someone to draw on my documents and they can indeed be saved with the drawings on them through downloading them.  I tested it. This is not supposed to happen as they are password protected. The system is failing to do what it is supposed to do. I called about a week ago and one of your employees did something which changed most of them,  except about 30 of the documents to a white background. This worked great, because now the ones that HAVE been changed also have the read aloud feature and can be translated into many languages. I am a teacher, so this is wonderful for my students. How can I change the remaining PDFs to a white background with the read aloud feature and how can I ensure that new ones are always white as well - without a drawing feature at the top? This has to be fixed ASAP or people will be able to ruin my documents. I would appreciate your help in this matter!
