Hello @Briggs, I never had problems with my DSLR, but lately very similar to you was my brand new smartphone, as described here: Cannot upload images to reviews - #6 by WilfriedB.
I couple of questions:
- Did you verify, whether your photos go public or are hidden, by sharing the link in an anonymous session?
- Do you edit your photos before uploading?
- Did you try after deleting a hidden photo, to crop it and upload again?
@MortenCopenhagen FYI: I still have problems will all photos from my Galaxy S24 FE and the all are accepted after saving with any image editor.
