Hi 
I sometimes have trouble trying to resize audio and MIDI clips and i realized (by capturing the following video) that it cannot be done at the 2nd zoom level … but we can still touch the grey squares so it’s confusing :
It’s a minor issue but that can be frustrating because vertical zoom isn’t intuitive in Cubasis 
i hope this will be considered for a better feeling using the app. 
I find to work better if I hold the finger on the corner of the event for 1 second before trying to resize, but never tried with different zoom scales.
Hi @electrafa,
Thanks for your message.
I gave the issue a short check on the iPhone X where things work as expected so far. Did you check out the tipp from @glainin and is it of help?
In addition: Please note that “pinch to zoom” via your thumb and index finger can also be used to quickly zoom in/out in the Arrange Window.
Hope that helps!
Stay safe,
Lars
