Since a few days ago, people receive an “error updating”. It will loads the latest activities. but stops, which is both annoying and plain bad if you have more than 20 new activities as it won’t download the remaining. This is due to another API change, the access point ConnectStats uses to download the power zones changed. So as quick fix, I removed the downloading of power zone and will add it back when I have a bit more time. A new version 4.4.2 is on its way with this fix.
Missing old activities
Quite a few people had issues downloading old activities. A new version should address the issue. If you were affected, once you have the new version 4.4.3, you should go to config, select Current Profile and Force Download Old Activities. This should try to download again everything.
