Ring updated

My ring updated yesterday. It really took a long time because the phone couldn't find the ring (physically next to it). Finally the update process finished, I put it on again and now (next morning) I can't have access to sleep data, any kind of data actually. The only thing I can see is battery level remaining. Basically it's useless right now. I've tried a soft reset but it hasn't worked so far. Has this happened to anyone? What did you do to solve the situation?
