Select documents and the app does....nothing

This app is clearly meant for iphone not ipad. I selected the documents to combine, pressed the “done” button and then......nothing. You only get the choice of selecting or deleting the document or just backing up through the choices to the first screen. This app is just completely useless.

Developer Response ,

Hi There! You are right, this is an iPhone only app.
To modify any PDF you have to open the file by tapping on it. In the new screen you're then presented with various modify options, including combining aka merging with another one (second icon from the right in the bottom toolbar).
Should you have further issues please contact our helpdesk or write directly to Thank you very much.

Safe, reliable, and necessary.

It works perfectly so far.
I am glad it is working as well as it is.
