1857363 - Mozilla VPN changes to just show a blank white screen, if you adjust your Android "System navigation" config while Mozilla VPN is open

Status: RESOLVED MOVED

(Mozilla VPN :: Client for Android, defect)

Description

[Daniel Holbert [:dholbert]]

STR:

1. Install and open Mozilla VPN. I'm assuming you're looking at the first-run "Sign up" welcome screen.
2. Switch to your Android system-settings app and search for the "system navigation" setting (search for "gestures" or "navigation" in the settings app)
3. Change that setting to the other option, from whatever you had selected (e.g. from Gesture navigation to 3-button-navigation, or vice versa)
4. Switch back to Mozilla VPN

ACTUAL RESULTS:
The app is now a blank white screen, with "Mozilla VPN" titlebar at the top but no other content. It stays this way even if I swap the Android system-navigation setting back to how it originally was. The only way to recover is to force-kill Mozilla VPN.

EXPECTED RESULTS:
App should still be functional after the settings change.

I'm using Android 13 on a Pixel 6a.
