Snippets Are Not The Same On All Devices
How to ensure your snippets are the same on your devices
If you are signed in to the same account on multiple devices, your snippets should all be the same on every device. If they are not, and your Snippets seem out of sync, you can sign out of the app, then sign back in. This will force the app to reconnect with the server.
A good way to double check what snippets are on your account is to sign into the web application located on TextExpander.com. Whatever you see in the snippet section after you sign in would be what is currently on your account.
