Bug report

I installed the app on my iPhone this morning as a trial before ordering the device, and it was working perfectly until I accepted the notification that there was an update. Ever since then the program has barely worked.. It took me four tries to get one brief transcription, and then that transcription disappeared. I have rebooted my phone. Now I can barely get it to hear me or respond like it did before the app update. Please let me know if a setting changed and what I need to do because at this point, I’m not happy with this program and not likely to buy the device unless this can get fixed.
