My Cloud OS 5

It is still being developed and seems to be a good app but I believe to maybe be a good app when they get done. I think the best apps were the older ones like My Book, no problems for others to use from anywhere like it was designed to do. The next best one was My Cloud OS 3. The upgrades don’t seem to get better for the user just WD because of the cost involving the need to buy new products (hardware) which puts more into the coffers of the company which looks forward to the haves and not for the elderly and have nots. But that is business and can be inspected. As a user it should be expected and the old addeged is “Buyer beware”

Just a tweak

I’m happy with the app overall but The old app had a progress bar for the downloads which made it easy to track progress would like something similar.

Could you also let the app show a preview of all files not just pictures.

Also, if there is a duplicate file please let the app download it anyway and either rename it or just have the duplicate name. I had downloads where it just stops because it’s sees a duplicate file. Very frustrating.

Accessing Photos Is A Pain!

I have [tried] to upload my iCloud Photo Library as a 2nd back up solution to my NAS using this app. The app itself does look nicer but all this does not help if I cannot view the photos on my other devices properly. I have 20,000+ in my library and all I get is this huge endless list of photos that takes a million years to fetch the images from every time I open the app. Surely there should be a way to cache the thumbnails locally for quicker access? Also it does not seem to upload the folders. Therefore I am stuck with an endless list of photos.

There is also no proper progress bar to tell me how many of my images have been uploaded correctly yet.

I am also getting lots of „oops ... something went wrong!“ messages when I try to look at my photos from a different view
