Hello, I've a couple of Android apps that worked well for years.
One of these apps has been recently restyled, and recompiled under VS2017. My big problem is that I can regularly download files from our external FTP server (Cerberus, no SSL), but I cannot anymore upload anything. There was no change in the FTP code, so I cannot wonder what it could be.
I've tested it on three different devices (Samsung SM-T550, V4.4.2, Asus Nexus 7 with 6.0.1 and a brand new Samsung Tab A6 with V7.0); if I install a simple app, like AndFTP, all the operations (download/upload) are carried out without errors.
I cannot paste an excerpt of the upload process taken from the Android Monitor, it exceedes the caracter's limit; the file I'm trying to upload is about 2MB in size.
Any suggestion is obviously welcome; if you need furter details please let me know.
