Version 31 has been released today.

While updating the desktop version, the following error will occur: “Sorry, an error occurred. The application cannot be installed due to a certificate problem. The certificate does not match the installed application certificate, does not support application upgrades, or is invalid.Please contact the application author.”

To resolve this, please uninstall the old installation. Then proceed with the installation of the latest version.

This is because the Desktop App is now being signed with a certificate from CA.

Thanks,
