I have a 2018 Q8. Using the Samsung app, I can upload a photo to the Ambient Duo mode, but the same photo won't be accepted by the Mono mode. The file appears to upload, but then the standard Mono picture remains and my photo is not available.
I saw one thread that mentioned setting the size to 1544x701 bit that didn't work either.
Is there a specific format or size that the picture must be? I've been uploading standard 16:9 and can't figure this out since the photo is accepted in both panes in the Ambient Duo mode.
Thanks for any help.
