PDF max pro This app used to work but now is totally useless. Please be warned that after the last iOS update if just freezes or crashes. The support team is incompetent and cannot even grasp the fact that there is a problem with the app. It has been months of trying to communicate with then the problems. After sending detailed information, screen shots etc. they write back with incoherent questions that have nothing to do with the app freezing and crashing upon opening it. They have asked me what document I ant ring to open when it crashes. I have repeatedly told them that it freezes or crashes upon opening the app and that that is the only action that can be made because it freezes or crashes just opening it. It is truly unbelievable that they still write back like they actually care with more ridiculous questions. My response is: what dont you get about the app upon opening will either crash or freeze so that no other function can be made on the app. I have no other clue to give them. So all of my important documents are lost unless they fix the app. Talk about upset. I have not been able to get to any of my PDF docs stored by the app for months. Would never again buy any app made by this company.
