Crash with iPhone 5s


I have a iPhone 5s with seafile application installed. When I navigate into directories, that’s ok. But when I try to access to a file (to open it), the iphone seafile application freezes and after few seconds the system automatically go back to the home screen.

I can’t tell you more details because I don’t know how to access to iphone logfile.

Many thanks for your help. Have a nice day.

the iOS version ios : 10.3.2 (14F89)
