Hi David,
Thank you for contacting us about this. Our Windows developer has been in contact with different support techs from Dropbox, and we're hoping there will be a resolution soon. When the issue is fixed, we will be releasing an update with the fix. In the meantime, if you are using mSecure 5, you can use mSecure Cloud syncing, as it is secured in the same way data stored in Dropbox is secured.
Thank you and looking forward for the update
David
"Dropbox recently updated their API's for app connectivity, and what they changed has broken the linking for Dropbox syncing in mSecure"
Is this issue fix? If not will mSecure releasing a new version to address this? Thanks
