Android issue : can't downgrade scenes on hierarchy

[Walden73]

Versions
Longform version: 2.0.7
Obsidian version: 1.5.12
OS [Android]:

I've noticed an issue with the MOBILE version of Longform, and I'm not sure if it's a bug or if I'm not using it correctly.
Basically, it's possible to upgrade the hierarchy of lower-level sub-scenes to higher-level scenes (swipe scene to the left), but I'm unable to do the opposite, to downgrade a scene inside another scene.

Essentially, I can go from:

1.Scene 1
1.1: Scene 1.1

to:

1.Scene 1
2.Scene 1.1

But I can't reverse this process.

Thank you for your assistance.

I have the same issue, but on iOS.

Also, use of the mobile app seems to destroy the hierarchy of the index, which makes me wonder if this bug is related?
