@ewpatton Thanks! I already downloaded testflight App and launched AI2 companion App from the testflight!
The first time I scanned the QR Code from PC, my program code launched and crushed when I tried to go to a location on the map. Afterwards, AI2 won't even start after scanned the QR code. I have reported both events in the bug reporting form.
Please tell me, could this error be the cause of my problem with uploading files to Dropbox? The same code works on Android, but it doesn't work on Iphone.
