Just got this and I want my $5 back. 1) It’s not opening a file that another PDF split and merge was able to open. This app claims it’s a damaged or encrypted file — it’s not. 2) You can’t view the pdf that you’re trying to split. So you have to memorize which pages you want to split out before uploading the file. 3) I waited for over a minute and it couldn’t perform a simple split. The app was still “working”.
