Hi. I have the same problem. As sooon as you want to take a picture (doing a scan), you see the word "capturing" and the entire app is frozen. I raised a ticket. They told me send the log file and screen shte. Did not help. Then they asked me to delete everythig and install the app again. I also restarated the phone. Re-installed everything. It still does not work. Further, the normal text search sometimes also froze my app.
I think there is a major issue with the version 10.46. Let's wait for Versoion 10.47.
