Maybe bc I haven’t updated…
For me it does MORE than it’s supposed to on the free version: rearrange pages in pdf, transfer files to/from anywhere I want (device storage, iCloud, & Google Drive tested); import pics in batches, make one or more into pdf, add/remove/edit order of pics in that pdf, & export created pdf anywhere I want. I’ve had it installed but never got around to using for a long time- maybe even a year or more. Now I’m clearing out old unused apps, and it’s been sitting on my to be updated list for a long time also. From so many neg reviews, I tried it with every expectation of deleting immediately. Instead, I’m thrilled with how much it does. Not gonna risk updating just in case. It is a bit clunky in the UI dept, but if you have a little patience, read the in-app FAQ, and know how to use Share menus to select/move files, you’ll figure it out like I did. If you’re impatient, dull-witted, or otherwise require an easier, smoother UI without having to figure stuff out, then resign yourself to paying for a subscription to full version Acrobat.
