Rectangle do not notify about available updates

[sigo]

I have enabled this option (Check for updates automatically) but never get any notification/alert about new versions or auto-update. Tested probably since 2 years at two different macbooks.

• [x] This is a new bug that hasn't been documented in a closed issue or in the Readme.

macOS version: 11.4 Rectangle version: Version 0.43 (48) ~~Logs if applicable (In Rectangle menu, hold option, "View Logging..."):~~

I've seen https://github.com/rxhanson/Rectangle/issues/194, and at the beginning I can show my plist settings:

> defaults read com.knollsoft.Rectangle.plist

{
    "NSStatusItem Preferred Position Item-0" = 421;
    "NSWindow Frame SUUpdateAlert" = "530 489 620 392 0 0 1680 1025 ";
    SUAutomaticallyUpdate = 1;
    SUEnableAutomaticChecks = 1;
    SUHasLaunchedBefore = 1;
    SULastCheckTime = "2021-06-17 09:38:56 +0000";
    SUSendProfileInfo = 0;
    SUUpdateGroupIdentifier = 766570249;
    SUUpdateRelaunchingMarker = 0;
    alternateDefaultShortcuts = 1;
    lastVersion = 48;
    launchOnLogin = 1;
}

Years later (sorry!), I never was able to reproduce this. If this comes up again, it's likely due to something preventing Sparkle from requesting or responding to an update. Meaning it would be something like a corporate VPN/firewall restriction.
