As the OS of my Asus C433 ChromeBook was recently updated to 109, the built-in Android version was updated to 11. In the meantime, I was able to use Android Evernote in the desktop interface, which is quite convenient. Please check if the version of Android is not updated. However, it is believed that the usability of Evernote on Chromebooks will be better once Evernote for Linux is officially released. However, as written in the above article, only 'Web App', 'Android App', and 'Linux Software' can be used in ChromeOS, and there is no concept of 'Software for ChromeOS'. Moreover, Evernote's share on ChromeOS isn't high enough to create a separate ChromeOS-optimized Android or Linux-based Evernote app, so I don't think there is a 'true Evernote app for ChromeOS'.
