We are working hard to identify all issues before they happen. From time to time there are weird scenarios that cause certain things to break.
We are working hard on eliminating those (with your amazing bug reports 🐞).
One of the known issues that happen sometimes is with Google Authentication or adding/deleting apps.
Here is how to fix it!
Navigate to Extensions window in the browser.
Then turn the Bardeen extension OFF and back ON to restart the engine.
This should fix the issue.
