After formatting Windows and installing dropbox on the new user it did not sync all photos. Dropbox did not uploaded all photos from the phone to the computer. I have over 5,000 multimedia on my phone from 2018 to now. Media from exactly one year have not been downloaded/synchronized. From August 2019 to August 2020 NOTHING was downloaded. Downloaded photos folder (on computer) is empty so there is space (photos moved to other folders) What can I do?
