My monthly graph had included activities in last July, but yesterday it suddenly disappeared.
I'm pretty sure this is the same issue reported in here,
https://forums.garmin.com/forum/into-sports/garmin-connect-mobile-application/garmin-connect-mobile-ios/1344644-incorrect-mileage-monthly-total
but nonetheless posting a new thread as the version 4.8 released today doesn't solve it.
Considering the Garmin Connect web can produce correct reports, I'm pretty sure Garmin App does aggregate values by its own but I'd suggest that it shouldn't. Just receives the data from the web and renders it. I strongly suspect the app has been maintained by a very small team without any solid specification or test suit (not surprised if it has no single test code) as this is not the first time it's clearly broken.
Or I'll stop using Garmin Connect and moves to something else (e.g. Today's Plan, Training Peaks). Hardly believes there exists any cycling training service run by people who're more indifferent to offering correct data. ciq.forums.garmin.com/.../1369604.png
