GUI Command Line Version not updating in MacOS

Having a weird problem that I just noticed. I have Duplicacy running in MacOS and Synology.

My Synology version of the Duplicacy GUI is using command line 3.1.0 which is current. However, my MacOS Duplicacy GUI is seemingly stuck on 2.7.2 which is years old now (it would have been ‘current’ when I installed Duplicacy on my MacBook at that time).

“On startup automatically update to” is set to “Stable” for both installs.

Any reason why the MacOS Duplicacy isn’t updating? Is there a way to force an update of the CLI version in the MacOS GUI?
