It works but that’s about it

So far, the new OS seems to be working. I miss a few of the features of the old system. For example, I haven’t figured out how to move a file from my phone to my storage device yet. So far, it looks like the only option is to copy files and that can be cumbersome when you’re copying from a long list of files that you really just want to move. If you have to pause the task in the middle of the transaction, it’s difficult to keep track of the number of files that you still need to copy. That’s the other problem too: there’s no way to know which files are in the process of being pasted and how much of them have been transferred. You only get to know the number of files you’ve chosen or how many files there are left in the transfer. The old system used to identify the files that were moved and specifically, which files were in the process of being moved.
There doesn’t appear to be any support for GIF images in the new OS either. However, the things that the new OS does do, it seems to do them well.

Software that is supposed to be an upgrade but is a downgrade. Perhaps the world of cloud - connected devices is so infested with malicious hackers that the only way to keep me safe is to severely limit what my MyCloud device can let me look at and download. In the privacy of my on home I can see a folder with 300 songs on my My cloud device - but there is no option for “download” - so how am I supposed to transfer those to my iPad? I can send a link and individually select songs. How about a choice for <select all> ?
Once again, WD has left the production of the User interface to access what my NAS can store sorely lacking in feature and usability.

Why do we have to go backwards

I have been using my cloud products for 10 years starting with my book. Now I’m on the PR2100 and it worked well with OS3. I mainly use the products for backup and enjoy the cloud access to files as I travel frequently. I have delayed updating to OS5 for sometime knowing it did not have the OS3 capabilities and had hoped that they would continue to complete the build out. But they have not. OS 3 is no longer supported and I have made the move. Seems very focused on pictures only. I cannot edit other file types in the app. I cannot save other file types from my iPhone or iPad to the OS5 app. So unless you just want to manage pictures from IOS this seems like a huge waste of having cloud access and does not have the functionality of previous versions although it was beta released in late 2020? Looks like it is time to find another backup provider with cloud access.
