Deliveries 8.4.2 for iOS Deliveries helps you keep track of all your packages, so you always know when they’re going to arrive….
Is Deliveries compatible with macOS Catalina? Why is "Add to Deliveries" missing from the Share menu?
There’s one notable issue with Catalina that we’re aware of: there is a bug where many third-party Share Menu extensions do not show up in System Preferences. This makes it impossible to enable the “Add to Deliveries” extension if it’s not already enabled. Apple is aware of the issue, but so far we don’t have any information about when a fix may be available.
If the extension is already enabled before you upgrade, it will most likely continue to be available, but if you rely on the extension then you may want to wait for a fix before you upgrade to Catalina. Of course if you bought a new computer with Catalina installed, this isn’t much help. Please see here for a list of other ways to add deliveries. The bookmarklet will work in Safari, though it’s much more limited than the Share extension, and Google Chrome extension is compatible with Catalina.
