If you feel like your data does not sync across devices properly (what you change on your computer, does not get changed on your mobile app etc.) you can do a sync health check to see what is going on with your sync.
The sync health check is accessed through the "help & resources" menu item at the top right.
Then select "Sync Health Check" to perform the health check.
You then see something like this:
Items that have a green check mark are healthy and anything that has a red triangle is causing a sync issue.
In this case there is no Internet Connection so Marvin can't sync.
But there is also something wrong with the user and password account.
As a rule if there is something not OK and you are not sure what it means, scroll down and send us a message through the contact form and we can help out:
Submitting a message through this form automatically sends us you sync health check.
