Weekly Mileage Bug (Shows 0.0)

check if will be this issue next week, maybe for the only the first week

I have a different bug on mine - or at least a different iteration. Mine currently shows 121.0 miles for the week, which is actually my mileage totaling from the day or two before I got the watch. 

I’ve seen this too.

Similar issue for me.  My weekly mileage widget currently shows 106.8 miles.  That total appears to be my total miles run since Monday, January 24th.  Today is Wednesday, February 2nd.  I would have expected my weekly mileage counter to reset on Monday, Jan 31st (my watch is set to have the week start on Monday's) and to currently show 21.7 miles (=12.0 + 9.7).  Seems like there might be a bug somewhere?

My watch is using FW 7.20.

Table of running mileage since I got my F7X SS on Friday, Jan 21st.

As of this Monday (1/31) mine has "reset" and is working properly. My weekly mileage is also showing properly on my built-in watch face. Prior to that, however, it was showing cumulative mileage from before I had the watch. 

Mine is still wonky, it says 0.00 for this week, even after todays run as well. and last week is this week.

After syncing your watch to GC try a hard reset - press and hold top left until shutdown then restart. Also try resetting the Run Activity to defaults - Run Settings, Restore defaults.

FWIW mine is showing a total albeit incorrect as I ran on Tuesday too. Reporting to Garmin Support now...

But what does a hard reset do?

I can’t be bothered to erase something just for a test.

Just like a computer reboot. Nothing is erased.
