sync failed: network connection failure

There is a totally annoying behavior in the new beta when you turn on auto sync feature. If you turn of wifi or if wifi is unable to connect to a network in regular intervals a popup appears saying: "sync failed: network connection failure" on top of which another prompt appears "Network connection failure". This is of course totally disruptive of focused work. Auto sync should sync whenever a wifi is available and otherwise keep silent. Perhaps you can offer an option to set an interval of x hourse to remind user "could not sync for x hours please connect to wifi" or similar. But current behavior is to me unacceptable.
