With the new updates I am unable to move items from my gallery to ##SecureFolder in my Galaxy S21 5G. It happened after the latest update. Earlier update stopped#WhatsApp being unable to download contents from Dual App, #Samsung pointed the finger at third party, now with Secure Folder. I am not too sure who to turn to now, I hope Samsung doesn't keep on saying us to use the phone without applications after spending some dollars on their phone, or ask us to reset the phone for something that happens to multiple user
I'm not sure if you were moving photo(s) in your gallery which was stored in a different album/location. I encountered the issue while trying to move pictures downloaded from my WhatsApp. A work around I did was to move the said pictures from the WhatsApp image folder (or wherever they're stored) to the "Camera" folder. Then, I was able to move the said photos to the Secured Folder. Hope this helps!
Had the same issue looked everywhere for answers but non worked for me. I found a way either edit the photo or take a screen shot and send it to the secure folder this should work 👍
