I noticed someone else reported this issue on iOS a couple ago, this issue also happen in Android since a year ago and it is still happening to me even after upgrading to the latest v4.1.0. Uninstall and re-install the app did not help.

Mobile: Google Pixel 5

App version: v4.1.0

Android version: 13.6.11

Odoo version: v15 Enterprise

The symptom is the same as the other post with iOS, as soon as I enter the 2FA code, the app would close. If I open the app again, have to re-enter all the login details. Even if login details are already stored by turning off 2FA for my account, then turn it back on, it still the same issue.
