Resize a Group Block just like any other Universe Block:
Tap to select the block. Then tap one of the corner handles and drag.
When resizing a Group Block it will crop the Block, not scale the contents. The content of your Group Block will remain in the Block and be visible if you resize your Block again.
Learn more about the Group Block here.
⭐️Want to see an option to scale the contents of a Group Block or other features on Universe? Reach out to our Support Team in the App or shoot an email to requestafeature@onuniverse.com.
