GC iOS 5.21 & 5.21.1 activities cannot been shown seperately one by one

After the update to GC iOS 5.21 & .1 the activities cannot been shown seperately one by on but all activities can been shown

When I go to more in the right corner at the bottom of the app and choose activities and the choose e.g. swimming there is only the running person animation and after a while the app closes completely

This happens always when I choose one specific activity

When I choose all activities I get a list of the activities immediately and can scroll through them

Please fix that
