So I installed from Australia as the US site won't let me. The message seems like it applies to future versions, not 4.21.10.0.
New features are coming to Digital Photo Professional around the first half of 2026, such as tailored notifications about news, offers, firmware updates and more. To be able to use the new version of the app, you will need a Canon ID. If you don’t have one, please create one and be ready for these updates.
