Yeah, I’m seeing your LifeMap as well. It may be that you have more data than your device/browser can handle. LifeMap is blank is a large thread that discusses the issue.
The Clear Map Data button that @jpbari is talking about is in the Profile section of your Settings page. That might help. It’s hidden for subscribers, because it isn’t really applicable - subscribers have an Advanced LifeMap which is way more performant and handles its data differently.
