I had many JPG images imported from Samsung S21 Phone and in my Lightroom-Catalogue and on my Harddisk.
Now, suddenly their size has reduced from average 6MB to 80KB and the large images have disappeared.
When I import large images again from my Phone, I get a new image on the harddisk, again with the small size of 80KB. (On the phone the images are 6MB, I sent images by eMail from the phone and they have the right size).
I have activated the converstion to DNG on import, but this is not done.
