I was flying at cruise, FL400, when unexpectedly the ECAM CAB PRESS EXCESS CAB ALT alert was triggered.

I’m not exactly sure what caused the cabin altitude warning, but when I switched to the external view, I noticed two openings/holes in the fuselage where the landing gear could be seen.

I’ve attached screenshots showing the ECAM warning and the exterior model.

Hi,

This was almost certainly caused by a misclick around the EFB while airborne, which triggered the window to open, although it didn't actually appear on screen. If this does happen again, you can verify by selecting the DOORS page on the E/WD, which is located under the engine start levers.

This has been logged by the team and has been fixed in v1.0.1

The issue shown in the second image regarding the gear bay doors has also been fixed in v1.0.1

Thanks!
