Simple Gmail Notes: Login Issue (2026-02-26)
Following a recent Gmail update, you may encounter this error after logging in: 'Error found with the existing token. Please try to connect again. If the error persists, you may try to manually revoke previous tokens first.'
We will release a new version soon to fix this. To work around the issue immediately, please navigate to the SGN preferences page (Click browser toolbar -> SGN -> Preferences) and enable the option 'Always use new window for login.'
Please refresh the Gmail page after saving your options.
