Wrong transition animation when going back via the left arrow

[pippi1otta]

Problem scope

• I'm sure that this is a DAVx⁵ problem.

App version

• I'm using the latest available DAVx⁵ version.

Android version and device/firmware type

Android 13 (Redmi Note 11 Pro)

Steps to reproduce

1. Tap on an account tile and see the new screen slide in from right to left
2. Go back via the left arrow in the top left corner

Actual result

The previous screen slides in from right to left, looking as if you opened a new one over the current screen.

Expected result

The current screen should slide out from left to right, looking as if you close it and reveal the previous one under it.

Further info

The issue occurs on other screens, like Settings, as well.
The transition is correct when going back via the Android Back button.

In the following screen recording, I first open a screen, then go back via Back, then open again and go back via the left arrow.
