Google task synchronizing error

I’ve got this message: Synchronizing folder “gmal address/foldername”
failed due to the following error: Constructor on type ‘MailClient.Storage.Application.Task.TaskItem’ not found.
What is the problem?

Hello Sharp,
could you please go to the third tab of the Operations window titled ‘Log’ next time this error pops up and copy its content here?
It should contain more information about the cause of this error.

Regards,
Olivia

If I change exist tasks on phone (done, modify content) then I get error in eM Client.
If I change every tasks in eM Client as I did on phone then will no error in eM Client. So full sync is not working in both direction.

Hello Sharp,
unfortunately this is a known issue at the time.
we are working on fixing it.
