On project creation, you can click the gear icon. In the settings, unselect "Pan and Zoom photos". This turns "OFF" the default setting and pan and zoom will NOT be applied to a project. The setting also remains sticky, so for future projects, the setting will remain "OFF" unless goes back in and turns it on. See attached video.
We have changed the default project setting. A Desktop project will have Pan and Zoom OFF by default and a mobile project will have pan and zoom ON by default. Again to point #1, these settings can be changed at any point.
Hope this helps and let me know if you have any questions!
