Could Tue problems be related to language Settings and timezone on the watch?
After 3.1.3 i reset My watch completely and resynced it from scratch. I also set the language to Danish, and now it stop almost instantly. I haven't Seen it Update for more than Half a Day before it freezes.
 
What was your language before? I'll have to test with Danish and see if I can repeat. I'll be tied up for a while though, so can't get to it right away.
