I have seen older posts about this so am writing again. Dropbox says by box has reached it's limit and I have to upgrade. I don't want to because I don't use it that much. I have deleted almost everything in it, so I don't understand why this is happening. I have had this dropbox for years and have consistently deleted things I wasn't using. I don't know why this is happening now. I have the basic service so can't contact anyone.
What can I do? This is very frustrating.
