When you factory reset your Pro 2019, it’s impossible your Pro 2023 got factory resetted as well (while you have to use a pin on the 2023, to use the setup/reset button).
Makes me wonder if you mixed things up by accident;
Are you sure you selected the Pro 2023 and not the Pro 2019 in the app?
To me, it really sounds like you are viewing the Pro 2019 unintentionally
