(This feature is only available in MightyText Pro)
If you have older messages on your phone that aren't yet on MightyText, it’s easy to sync them to MightyText.
In the MightyText Web App, navigate to Settings > General > Sync Older Messages from Phone. (In the Tablet app, navigate to Settings > Storage/Deletion > Sync Older Messages from Phone.)
In the web app, select how far back you'd like to sync, then click Get Older Messages. In the tablet app, click Get Older Messages from Phone and then choose the duration you’d like and the sync begins!
This might take a few minutes, so be patient. To avoid duplicate messages displaying in MightyText, don’t start another sync until the first one completes.
