MyCloudEX2Ultra 5.19.117 Lost all APPS

All of the apps disappeared. I tried a factory restore and they didn’t return. How do I get the Apps back? I am trying to configure for MyCloud to remote MyCloud backup.

I have this same issue on multiple MyCloud EX2 Ultra devices. I have tried the steps in the link on the knowledge base.

When I try to install it says the install failed.

Are the apps you are trying to backup specifically for OS3? If so, they will fail.

@retired25 Did you update OS 3 to OS 5 5.19.117 directly ? Or you updated from prior OS 5 versions ?

If you have updated directly from OS 3 to OS 5, I would like to share the below 3rd party Matrix.
