Hi, verified as fixed on the latest Nightly Build 200708 from 7/8 using the following devices: • Google Pixel 3a (Android 10) • Huawei Mate 20 Lite (Android 9) • OnePlus A3 (Android 6.0.1)

The Save logins and passwords, Sync logins and Saved logins are disabled after the user exits the Saved logins section.
