Lightroom mobile Android: Blurred images in Rate/Review View

I switched from an Ipad to an Android tablet und installed Lightroom mobile yesterday. I am not sure if it is a bug or some kind of settings I cant find. But on the andorid tablet (and it is the same on my Android Pixel Smartphone) when you get into the Rate/Review View to flag or mark pictures, all images (RAW or JPEG) are blurred until you click on the flag or star button to rate the image. Then the images gets instanly sharp. That problem somehow makes the Rate/Review View useless for me, because I cant go through my iamges fast.

On my Ipad Images in the Rate/Review View were all sharp from the beginning.

Anyone an idea how to fix this problem?
