Please ensure you are logged into the same account on the Desktop App and Splice website.
To check, go to the Preferences section of the Desktop App to verify it is the same username and e-mail as the Splice website: https://splice.com/profile/settings
If you have confirmed you are logged in with the correct account, but the Desktop App is still not recognizing you, please do the following:
Uninstall and reinstall the desktop app. You can get the latest installer here: splice.com/download
If reinstall does not solve this, please clear the Splice app cache. To do this, please follow the below instructions depending on which OS you're running.
