Too many issues

From worse to bad:
- Re-uploads photos already uploaded (at least if you quit the app before it’s done uploading the entire library) resulting in duplicate photos and sets in Flickr (allow deletion setting is checked too)
- Requires 2 extra in app purchases to get the full functionality
- Asks to reauthorize Flickr everytime the app is launched
- Does not remember the selected iPhoto library when relaunching
- Prompts for new version available (2.9.4) at every launch while the app is already at version 2.9.5 from the App Store
- Uploads only 1 photo at a time
- Pauses several seconds between each photo upload
- Progress bar behaves erratically by going forward and backward during uploads
- App did crash once after pausing the transfer
