It looks like Dropbox changed things on their end so that their recommended approach for how UWP applications should connect no longer works. Luckily I had already implemented a workaround for this, so I'm going to put that workaround back in for the next update. Hopefully this workaround will suffice across all devices, as it did seem to behave a little oddly on some in the past.
