LrM Slow Crop and Loosing Edit

Hi,

I'm on Android (Galaxy S20 Ultra). It has been working fine for me until recently two things changed. a) New LrM with changed GUI and b) I moved Lr to the external SD Card (writes solid 40MB/s, so works fine).

The issues:

Cropping images is very slow. The more often I crop the same image, the slower it gets it seems (maybe a memory leak).

Sometimes the app keeps displaying me the message, that it's running to slow and if I want to exit it or wait. Waiting continues operation of the app, but rather sooner the message appears again. Often times the app will run quite a while without that issue.

Sometimes when I edit an image, the image suddenly closes and I'm back in the browser. All changes I made since the opening the image get lost.

Cheers
