The RootsMagic App has not been updated to accept the new RootsMagic database (.rmtree) file. Instead we have created an export option inside RootsMagic that will send the database with the correct (.rmgc) file extension for the RootsMagic App. Go to File, Export Data, Dropbox to upload the file to Dropbox which then can be downloaded by the RootsMagic mobile app for iOS devices.
