Problem
1. Previously imported png skins (prior to latest update) no longer render/apply
2. imports from photo picker are failing despite the photo having the right file type and size.

With respect to 2, upon choosing an image via photopicker, the following error message is displayed.

Expected
1. Previously imported skins, which are still seen and selectable in-game should be applicable, and not default back to a default skin when returning from classic skin menu.
2. Photo picker imports of valid file types and sizes should import and render.

Workaround
Wrap classic skin png in a skin pack per https://learn.microsoft.com/en-us/minecraft/creator/documents/packagingaskinpack?view=minecraft-bedrock-stable

In my case, I used a Mac to create the skin pack files and directory, zip it, rename the file extension to mcpack, and share the mcpack file via airdrop to my iOS device.  After that, just open/import the file with Minecraft.

NOTE
The attached skin pack contains the original png which failed to import directly.
