Untill recently Iused to sync 2DO with Dropbox.
I Changed the settings in my Ipad to sync with Toodledo . This is the fierst sync with Toodledo and the syncsetup "declared" that the next sync action is : " Merge Sync" I continued with the syncronization and got the next message: " Sync Failed The following error occured during sync: Invalid API Key , could not establish connection , Please try again later".
Indeed, I did tried few times but got the same message.
Appriciate your help
