Elements are cropping or shifting on mobile
Screenshots show one of our templates. Yours may look slightly different, but the steps are the same.
Lock it. Select the element and click the lock icon in the toolbar. This stops it moving or resizing when the layout adapts to mobile.
If that doesn't fix it, check the section is still grouped. Canva's mobile layout depends on groups.
Always check the result in Preview with Resize on mobile ticked.
