Hi, thanks for your reply. WebAccess is installed in an Android 9 running on a moto G(6), NAS Bufallo LinkStation LS210D. As for firmware, in theory the last version since the update option is enabled and there is nothing to update when checking for new version. I found "Version 1.70-0.01" at the bottom of the GUI if that works for firmware version? Any clues why the photographs are downsized?
Also, if I use a different Photo Sync app, the pictures are uploaded at their original dimension and resolution. Therefore maybe something not working right in WebAcccess? thanks for your help.
Without knowing what NAS / firmware / version of android you have it's impossible to answer!!
