Call Recorder Pro: Dropbox maintenance
Due to changes in Dropbox API: The synchronization is deprecated now in Dropbox. More you can read here
We are working on including new Dropbox API into Call Recorder Pro so it would work as before.
It will be available in the next app update (Call Recorder Pro ver 4.5 ) that will be available from 06.06.2016
Sorry for inconvenience.
