What Android version is on your device? The minimum required has recently changed to Android 10. As you have found, if you uninstall you will not be able to reinstall if using a previous Android version. So as long as you don’t uninstall, you will still be able to use the app.

I have on my Samsung Note8: Android 9
I should update it to version 10

If you are able to update to Android 10, that would be the answer.
