Access to Dropbox gone?

I have two devices (Inkpad 2 and Touch HD) and I use the Dropbox sync often, but a week ago or so Dropbox stopped connecting and trying to login anew did not work on either device. Thus far I had refrained from updating the firmware on the devices, but then I did it. After the firmware update, I got connected to Dropbox on Touch HD (had to log in afresh), but no such luck on Inkpad 2. Anyone else experiencing the same?
