I have 7 'Other Lightroom Mobile device' tabs. Two of the tabs also shows my Samsung GT-19505. When you click on the tabs no photographs load. There is a ? next to all the 'Imported Photos', apart from the ones relating to the Samsung phone. When I try and link the folders, I get a pop up saying 'An internal error has occurred: a source is required to change a folder location'. LR looks a mess can you help please?
