I would ask, did the sprinklers run when expected but the concern is no visible history?
There are known issues with the backend and possibly the recent app update. If the timers are running on the expected schedule, best to leave them alone and wait until the bugs have been worked out.
Going after resets and reprogramming when the backend systems are having issues is just going to add frustration and difficulties getting things set back up correctly. (I have two devices that cannot be registered at the moment. Support: ‘We are having trouble with the app.’)
