OP-Z tape track graphics in iOS app

Looking at Red Means Recording’s video, looks like on the tape page there should be a red sample area which is a subset of the black ‘waveform’ with width dependent on black piano keys and position dependent on white piano keys.

I just get a red vertical bar representing the tape head.

Also, the tape reels just keep spinning rather than stopping, starting, reversing etc when using the white keys.

Any ideas? Is this normal with latest software?

I’m on the latest firmware and app version.
