"Update All" is broken

When there are a lot of updates available and I click "Update All", there are a lot of problems:

• Some apps seem to get downloaded, but it never prompts to install them
• Some apps get the install prompt multiple times
• Just after clicking the button, it does not change to "Cancel," it just stays grayed out
• After moving between pages in the Aurora app, after going back to updates, the cancel button is there, but it does nothing
