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!
Too buggy

Would love to use this app, but screens don’t load or get stuck in odd layouts. Clearly a lot of work to do before it’s ready for real users.
Can’t get it to work
