Valid 64x64 skin not accepted on Bedrock Beta Android

In Minecraft Bedrock Beta 1.21.80.28 on Android 14, I tried uploading a custom 64x64 PNG skin through the Classic Skins menu. The game shows an error saying "Please import a .png file of dimensions 64x64, 64x32, or 128x128," even though the file is a valid 64x64 skin.

Steps to reproduce:

1. Go to Profile > Classic Skins

2. Tap "Owned Skins" and choose to import a new skin

3. Select a 64x64 .png file

4. The error message appears

I

tested this on a Lenovo Idea Tab Pro tablet. Restarting the game didn’t help. The file was downloaded from a skin website and is correctly formatted.

This appears to be a bug in the beta build.
