Still lots of bugs
It took a year or so for the developer to update this app!!! Even with the latest update, the app still contains so many bugs! On iOS 13.1, iPad Pro 10.5, I used this app with a Y-shape card reader 4-in-1 as guided from the maker: - unable to transfer videos between the external device and iPad. - unable to play video from the external device. - able to copy photos from the external device to iPad smoothly, but to transfer photos from iPad to the external device frequently crashed. It could transfer 30-60 photos then stopped. - the speed to read both external and internal device has been improved a lot compared to the status before update, but it is still unstable. Crashed frequently! Please fix those bugs to make this app as good as when it is used with iOS 10.3.4.
