Smile has acknowledged a bug in TextExpander touch 3.2.3 (released on 7 April 2015) that “appears to erase all your snippets.” Fortunately, the snippets aren’t really gone, just inaccessible. A forthcoming update to TextExpander touch will restore them, or, if you use Dropbox for snippet syncing, you can recover them from Dropbox. The bug and methods for dealing with it are fully documented in the Smile blog post. The most important takeaway is this: Do NOT delete and reinstall the app, which could cause you to lose your snippets irrevocably! follow link
