1: indicating the server’s address took some trial and error. I had to add a trailing / for the address to work => The app should be able to find this by itself.
I remember that indicating the server path using the stable app the first time felt rather unhelpful as well so maybe the process is already getting easier but still not easy enough
2: on the stable app, it is not possible to select a large chunk of photos and upload it. Not only there is no “select all” feature but there are other problems: If from Photos, the app will not even propose you to upload the selected photos. If from the app, then the app will crash if you select too many photos.
With the Alpha version I still can not select anything to upload. But when it’s available I hope the p. m. issues with the stable app are addressed.
