• I made doubly sure this is not a checksum does not match / SHA256 mismatch error (do not open an issue before trying to open a PR to fix first).

Description of issue

When updating ExpressVPN using brew upgrade, ExpressVPN behaves as if it is a fresh install, meaning all settings and preferences are lost when I reopen ExpressVPN and I need to sign in again.

Seems like right now the uninstall script will run during update which may cause the removal of user configurations.

script:    {
              executable: "/Applications/ExpressVPN.app/Contents/Resources/uninstall.tool",
              input:      ["Yes"],
              sudo:       true,
            }

Does this app auto updates itself? (ie., the app will check for update upon opening and ask you if you want to update or alike)
Looks like yes according to their article, but I never used this app so would like a confirmation.

@yunhao-jiang I believe it does but a) I've never actually had it auto-update since I've always had Homebrew update it first and b) there was a PR #144246 to remove auto-update last year and a related discussion #143794 though it seems to have been working as intended #143793.

[yunhao-jiang]

@martimlobao Thanks for the references. It seems the removal of auto-update is prior to the software actually supports the auto update, which make sense. I think we could add it back so that brew upgrade will ignore this.
By looking at the uninstallation scripts that ExpressVPN provided, it seems they will perform a "zap" like action that removes all user files.

I guess the best fix for this as for now is to add the auto_updates back and let the application handle the update on their own. It is certainly possible to reimplement what's inside their uninstall.tool and leave out the user files, but it would be hard for us to sync if they update their script. Plus, running this script seems to be the official way of uninstallation.

These are my two cents.

[krehel]

The uninstaller does look as it removes everything so the uninstall should be rewritten to only remove necessary files for upgrade and push the uninstall script to the zap, similar to private-internet-access IMHO.

I'll get around to this, (if someone else wants to first, feel free) but it may take me a day or two and I will need a willing tester as I don't use ExpressVPN.

@krehel happy to serve as a tester if you need me
