Tried to set up 2 different account, on yahoo and one gmail. After providing needed info, it says “syncing info” but the sync goes on… and on… and on. After half an hour (each) I gave upl. And the link in the App Store to app support can’t find the site. Update: Opened the app again and actually got to my yahoo mailbox. However, the connection failed. I did find a link to Support that opened a messaging portal so sent my report. Got an answer within a couple of hours that they are aware of the problem and are working on it. And all this on New Year’s Day!
Can’t get it to work
