I opened 6500x5000 px files into PS Touch in iPad for some minor retouching. PS Touch - without notification - reduced the images to fit within 2048 x 2048 px. It happily let me open these files, work on them and save and never let me know it was reducing the file size, rendering all the work I did utterly useless since 2048x2048 is far too small for print res for these files.
PS Touch needs a notification or warning when importing files larger than the app's max resolution. Resizing files without notification is just asinine.
Thank you - done.
