I have the iOS app for adobe Photoshop and I stopped working on my project for a bit, went back to access it (I did save before hand) and it won't load, the loading animation is all that shows and nothing else. It's been doing this for 30 minutes or so. I've tried refreshing, shutting the app and turning it on, shutting off my iPad and turning it on again and nothing.
We don't deal with IOS applications in this forum at all, only with Photoshop proper for Mac and for Windows.
Are you on something like Adobe Photoshop Touch for tablet?
