I am experiencing this on both Bakery Story and Fashion Story on two separate devices. First device is iPad Air 2. Second device is Samsung Galaxy S4 with dedicated 4G connection as well as wifi.
Both games are slow to load wall posts and community listings. Every few minutes I am disconnected from the server with an alert message that both games require internet connection to play. When I click 'Retry', the games reconnect, but the cycle repeats every few minutes.
My internet connection has been stable all day. I have also tried connecting via the 4G network, but experienced the same issues.
