Hi,

Try using a mobile browser like Chrome or Firefox to log in - Odoo is responsive and works well without the app.

Check the Odoo app’s permissions in your Android settings and ensure necessary permissions like internet and storage are enabled.

Sometimes logging in once through the browser helps initialize credentials for the app.

Use the desktop version temporarily if the mobile app remains unusable - access via browser on a computer.

If you're able to, test the same login on a different Android device to check if it's specific device.

Odoo may release an app update for compatibility with latest versions - keep checking update the latest version.

Hope it helps
