Sometimes Showbie will not be in the selection of apps when sharing files but here’s how you can easily change that!
Check if Showbie is hidden in the list
- Scroll to the very end of the list
- Tap More
- Tap the slider next to Showbie so that it is green
- Tap Done
- Now Showbie should appear in the list!
Also, check if there is an Open In option (instead of More). Tapping this should bring up another selection of apps that includes Showbie.
