Google has unceremoniously ended support for Keep and Maps on Wear OS 2 smartwatches. That means, if you reset your older wearable, you won't get to access these apps again. The most recent version of Keep on the Google Pixel Watch is 5.22.452.00.97, and it only supports Android 11 or higher. (Wear OS 2 is based on Android 9, which falls behind the latest version of Keep.) Maps also seems to limit its requirements to the latest version of Wear OS. The change might seem premature as most Wear OS smartwatches are still on Wear OS 2, but it seems Google wants to move to Wear OS 3 as soon as possible.
