There is no swimming charts show on the new version of 4.13.2. It said "this activity doesn't have any charts". This happens with all my swimming activities, while running, cycling, and other activities are still there. Therefore, I have to visit website to get information instead.
Happened to my husband today too. I swam yesterday, have the previous version of the app and my charts are there - either a server issue or a bug in the new release. :'(
