The app needs a lot of improvements in terms of user experinence. They should give a easier navigation pattern to search and view prototypes. They should allow the user to refresh the prototype once opened and cached. They should have a recently viewed section to view most recent viewed or updated proposal instead of going in to specific folders which is itself is scrutiny. they should integrate the exported links managment within the app so dev and designers can directly manage links and see the status and comments from the app. Currently this is the only app that allows users to view the XD prototypes so I guess we are bound to use the app to view protos on android. I wish they could do the same to this app as they are doing on Windows and mac. I.e. periodic updates to make exp better. Currently I have to export all the screens to Invision app to get the good exp.

Update after dev comment: So i was initially unable to open a new document to use in the app, except for uninstalling and reinstalling. I got feedback that you have to long press the screen to access the menu. Adobe, it would be very helpfull if you add hints or overlay tutorial in your app if you want to use such methods of navigating. A small simple 4 second note each time you open a cached document "longpress to access the menu" would help a lot. I gave this app 2 stars before because i thought this was a bug, but now i will give it 1 star because this is an app that is linked with Adobe, usability, design and experience. It should not need tutorials and step by step guides via Google Play feedback to use basic functionality.

Are you being serious?? Or am I horribly missing something here?? Can't find any main app control once I start a prototype. Closing the app is making it load the file from cache and starting the prototype again!! It can't be this bad right. What am I missing here??

While the functionality is basically there and it's nice to be able to show off designs on my tablet / phone... Fonts seem to be a problem. Can't design with certain Fonts in mind and then have the design not be able to use them. It's not obvious how to rectify such a situation.

How to change document, after opening another one? When I go app the app close. When I reopen it it opens last document from cache. But I would like to see other projects.

Crashes at 90% loading of a doc through CC. Didn't work by USB. Edit after comment from team: USB tethering didn't seem to work. The UI on the phone simply flashed between showing the XD logo and saying "open an XD document on your desktop to see the preview here" or something along those lines. Tried by saving my XD file into my CC library and opening it on my phone, it would load until about 90% and the Adobe XD app would simply crash. It was a pretty big file to be fair, (125mb) maybe there's some sort of upper limit on the filesize for mobile preview?
