Last week I upgraded from macOS Mojave to macOS Catalina – but many of my programs went grey with the question mark. Yesterday, I backed up my computer and downgraded back to macOS Mojave.
After adding my files from my backup, I found there were now 2 HD's on my desktop, Macintosh HD and Macintosh HD Data. I'm not sure what this is about, so if anyone has an info – it would be appreciated.
I went to the Mac App Store to download previously purchased or free apps that I had, like Keynote, Pages, even Solitaire, I get these 2 different messages.
The first is below, the second just says "cancelled".
Any ideas on how to fix this?

This is expected behavior in macOS Catalina. Refer to the Apple Support document, About the read-only system volume in macOS Catalina
This is apparently a server side message from Apple. Try again after some time and make sure you have an active Internet connection.
