How can this be?
 Seems legit though, what's the catch?
		
		
	 
This is just from my perspective, but one being have to have a Canva account (doesn't have to be paid, but do have to have an account with them as well).  
There are features (which wouldn't appeal to me, but I'm probably in the minority) that are still locked behind the paywall.
This is a one way ticket for existing files.  There is no backward compatibility.  So if mixing/matching between old apps and new between different platforms, that could be an issue (I do think there is a lag between desktop and the more mobile platforms with regard to this update (or updating in general), but I could be wrong).
Of course, there are redesign UI concerns, but that happens from time to time regardless of the app.
