The app image I downloaded after becoming a supporter works nicely on the Jammy Jellyfish I installed on my laptop, but not on this RPi4 also running Jammy. I did install a version of fritzing on this RPi4 from the repository and it worked. Is there a way to upgrade my installed version to the latest? Or is there an app image of the latest version for RPi4?

The developers sometimes read the forums but github is the official tracking place for bugs.
