Just installed a new 65" 2020 Frame TV.
Only 4 custom pictures have been saved to the frame. Yet when I try to add a 5th I'm getting an error message on my SmartThings app that the Frame TV is already out of space????
The specific error is "Insufficient Storage - Not enough storage space on The Frame. Delete some images and try again (04211)
From further research, there are a lot of people with this same problem. It is due to a BUG where the memory fills up on the Frame TV's.
DO NOT BUY ANY FRAME TV's until Samsung fixes this serious issue.
Same issue here. I had to reset the TV, then I could upload images.
The issue is from Ambient Mode. I was using that and it filled up the memory. Even though the TV said it has available memory, it wasn't available.
