Lazy Developer
I dont understand why developers are allowed to Keep their content in the app store when it is not compatible with the most recent version of iOS. Well using the most recent version on an iPad Pro… You are completely unable to open a single PDF file. It was pretty clear this was going to happen from the moment that I saw screenshots that were out of date on the home screen which provided instructions on how to open PDF files. It simply doesnt work!
