Here also shows the reduced size in KB, the sync status is kind of ok. It looks like the original ORF files were replaced with smaller and worse quality. Of course, the problem is only with photos that were edited earlier. now, when I throw the same file again, it's kind of ok. I was away then, and the photos were uploaded from the mobile app and the camera's memory card. I don't know if it matters.
I work on a PC at home and I have optical fiber so internet is not a problem either.
