Input errors RealVNC Viewer on iPad

Very weird, but is anyone else experiencing the first two letters typed into Terminal in RealVNC Viewer on an iPad (Pro, iPadOS 15.0.2) being converted instantly into the letter “v”? If the “v” is deleted and the command retyped, sometimes it happens again; sometimes not.

Note that the keyboard VNC symbol (auto-dropdown at top of window) has to be invoked to get any input to appear at all.
