Load a song in your library, tap the center of the screen to bring up the song overlay, tap the second icon at the bottom left, tap Zoom/Pan Settings, and then change the dropdown for "Text and Chord Pro File Zoom Mode" to "Disabled". Then zooming won't work for chord pro files. You could also change it to "Change Page Size", and then zooming in on chord pro files will work like it does with PDFs where it just increases the size of the rendered image. The annotations will then stay positioned correctly as you zoom in.
