Syncthing URI address not correctly updated after test (implicit save), must restart Syncthing

Syncthing Tray command "Open" and Preferences window button "Open Syncthing Web Interface" defaults to 127.0.0.1:8384 irrespectively of actually entered value. As a result "Connection refused"/"Couldn't connect" message appears as the Web browser is directed to open the default 127.0.0.1:8384 address. The manual entry directly in address line works correctly

Sorry for the delay. It seems indeed a bit odd. When de URI is input + checked and saved with the Test button in the Preferences window. The Icon -> Open menu item and Open Syncthing Web Interface use the old value and probably not the default 127.0.0.1:8384.

There is a workaround (yes it is very odd):

• Click the icon -> Go to Preferences -> enter URI -> Test (click to check Syncthing connection OK), the button bullet must be green (then the URI is saved
• Click the icon -> Quit Syncthing
• Start Syncthing

Thanks for reporting, it is easy reproducable.

EDIT:
It is even more weird after further testing. Setting the URI, then Test OK with green bullet in the button. Then the preference window is closed. And reopened and the old URI is in the input box. That is what is happening...

I couldn't make the preference change persist either. For now, I just manually set the URI value in the preference for a workaround, for example:

# quit syncthing-macos first
# back up
cp ~/Library/Preferences/com.github.xor-gate.syncthing-macosx.plist ~/Library/Preferences/com.github.xor-gate.syncthing-macosx.plist.bak
# overwrite with desired URI
defaults write com.github.xor-gate.syncthing-macosx URI "http://127.0.0.1:8385"
# start syncthing-macos

Ultimately, it may be better to keep the syncthing core setting (in config.xml) as the source of truth and drop this macos app setting.
