ios: unable to export large number of files from workgroup

[hantt12]

Description

App shows exporting dialog but then closes without asking user to save file

Steps:

1. Go to Shared Space
2. Select large number of files at once
3. Export

Expected result

Show exporting files dialog and then ask user to confirm to save file

Current behavior

Exporting file dialog is shown but then disappear for a while. Nothing more

NOTE:

• Not sure this is related to the total file size or number of files.
  My first try: 29 files with 70.4MB of file size in total => able to download
  Another try: 29 other files with 72.2MB of file size => Not able to download
  Please dig more into it
