Sourcetree doesn't notice changes for certain locations on the filesystem. A simple test in screenshots where you can see the ST won't show the updates until I restart it. Git happily shows the diff.
I'm suspicious this is something related to Catalina's readonly filesystem. My working dir is `/data/development/ios/adia-ios` where /data is symlinked as per `synthetic.conf`
[msp@Ra adia-ios (656-mixpanel-tracking-ios)]$ cat /etc/synthetic.conf
