Google linking no longer works

Since May 30th, 2022, Google have disabled the ability to use less secure apps. Therefore, when enabling the ‘Labs’ Google calendar and Google tasks features, I cannot sign in as Google blocks it (due to it being less secure).

@Sennen Yes, it is not possible to connect Google Calendar now because of that restriction (unless it was connected prior to that).
Google Calendar integration will be migrated to next-gen dashboards later this year. At that point, the app would go through Google’s approval process to use those APIs without restriction.
