I have been using the "Add Attachment" feature on my iPhones email for very long time with no issues. When clicking "Add Attachment" I am normally moved to a menu where I can select "Locations" where to pick up files and amongst the "Locations" I can choose Dropbox and then scroll thru my Dropbox files.
All of a suddent this nice feature disappeared:-(
On the "Locations" list I can only see "iCloud Drive" and "my Iphone", Dropbox disappeared!
Anyone has any idea why and if/how I could fix restore this nice feature?
