Working with multiple projects in IOS

I have two separate projects (2 volumes of one “Novel”) in Scrivener IOS. As I continue working on Vol #2 I sometimes need to go back to Vol #1 to revise a backstory. Is there any way to essentially, I guess, have two projects (or two instances of the Scrivener App) open simultaneously on IOS or must I close one and then bring up the other afterward?

Thanks.
Don.

So far as I know, it’s one project at a time.

However, if you’re willing to merge the two novels into a single project and use a PC or Mac to manage them at compile time, you can work around that.
