Hey @shaynat77390126 -
I am updating this thread so others who have access to the dynamic QR codes feature have the latest update!
There's no cap on how many dynamic QR codes you can have -- the Manage panel shows the 3 most recent by default, but you should be able to scroll to see older ones.
The key thing to check: when you generate the code, make sure to have the "Track QR code" toggle turned on. That's what makes it dynamic and editable after the fact. If that toggle was off, the code was saved as static, which means the destination URL can't be updated -- the fix in that case is to generate a fresh QR code with the toggle on.
Let me know if you have further questions!
