Wifi loading worked until Oct 5, 2017 – File Manager & Browser Review

I've loved this app. Had it for years. It updated by itself, and now I can no longer upload files from my mac desktop via wifi. When I click on the button to go to the wifi, the app crashes. I've rebooted my iPhone 6plus. Still crashes. Please fix, otherwise this app is no use to me any longer.
