I'm really sorry Capture isn't working as it should be. It's a known issue in the app and the team is working on a beta version with a fix. I'm hoping it will be available before the end of the week, but I'm not completely certain about the timeline.
I do know that we'll be releasing it on Adobe Android Apps - Community - Google+, so join that page and you'll be notified as soon as it's available.

This was an amazing description of the trouble you're having. Thanks so much for going into so much detail. It makes a huge difference when the engineers are trying to figure out what's going on.
Please post here or contact us through the app (tap the Draw icon, then Give Us Feedback) whenever you need help. Sometimes on the weekends I'm a bit slow but during the week I try to get to people as quickly as possible.
I hope that helps.
Thank you for your response. This morning (May 05, 2016), an update for Adobe Capture was available, and I dowloaded and installed it. All application functionality seems to be working correctly now.
Happy to hear everything's back to normal.
