I had trouble doing more than 1 session of 40 pictures. Is there an open issue going further on Android, or is this just me having this issue?

Hrm. It's not by design and we can't reproduce the problem. It could be a memory issue in the app. We'll try to see if we can figure it out.
There shouldn't be any limit on the number of pictures you can go through. The issue you're seeing might be because of a low-memory issue on your device. At the moment this feature is not totally optimal, as it loads all of the image suggestions into memory at once. Depending on your type of device, and what other apps might be running in the background, this feature's high memory usage might be triggering an out-of-memory condition. Future updates to the feature will optimize memory usage.
