iPad not showing full screen

iPad not showing full screen

I am trying to use Vault on an iPad Pro, with most current iOS. The right-hand side of the screen is cut off, so I cannot see the actual password or read any notes.

There does not seem to be any menu with settings, tools, or other options visible in the iPad version.

The program appears to work on a PC, but not on my iPad.

What is needed to fix this?
