Question iOS Memory optimization

Hello!

I took a snapshot of our game using GPU Frame Debugger and sent it to Apple developer who checked the captured frame.

He gave us some tips to help us improve our productivity:

1) All textures remain in shared memory and we need to transfer them to private memory.
2) We have a lot of unused textures to release. (I tried calling AssetDatabase.ReleaseUnusedAssets () but it didn't help)
3) We need to remove the PixelFormatView flag from textures

I tried to find information on this, but unfortunately I couldn't find it.

Maybe someone knows and can share information on what I need to do in order to solve the problems described above.

Thanks in advance!
