1. Whenever I leave the document and come back, the edited version flashes on screen for a moment but is immediately replaced with the original document from before i made any changes.Top-notch app that I use for everything relating to taking visual notes on PDF text.

2. Just not an intuitive app.This is THE Worst App I Have Ever Used! Do NOT waste your time with this app! Find an alternate app instead.. It is not user friendly, no scroll bars and not clear how to save the doctor paper you worked so hard to complete for the last 4 hours since the app is HORRIBLE! The paperwork went in & out of focus as did the text of the questions I had answer.

3. I made a couple of docs, and everytime I click "download" it says, "successfully downloaded" but then when I go to check the doc out in my downloads, it is nowhere to be found! This is frustrating because it works just fine online, but the mobile app is a let down.I have stopped my subscription but they keep deducting monthly fees from my Credit Card.

4. My only complaint is that some features that exist on mobile don't exist on the Windows app and web version so it's tricky keeping my notes consistent looking.The browser version only requests access to the files you use with Lumin.

5. Because there are no scroll bars you have to use 2 fingers on the empty space on either side of the document & even then sometimes does not workWhenever I edit a pdf it doesn't save.

6. Also, when I want to zoom the document, the screen doesn't adapted to it, you should be able to hide the hud so there's not to many elements on screen.

7. You can't directly go to the page you want, you need to scroll it down until you find it, which is very annoying if you're reading 900 pages pdf.

8. Overall, not very useful app for reading or editing pdf's.The app is great and easy to use, but it lacks the crucial feature of DOWNLOADING YOUR EDITED DOCUMENTS.

9. That's whatsup!! That is a good business.The app was promising which made me purchased the subscription, however it turned out to have a lor of bugs with very week technical support.

10. Because although it wasn't what I needed as far as editing pdfs -- the very same day that I contacted them requesting a refund because I forgot to close my account after the free trial -- the same day they refunded me the $30.

11. As soon as I touch the document to scroll down a massive redline is drawn across the page.
