There's something wrong with the way you're calculating my XP!
Your Artist XP is directly related to your Stars - you receive both Stars and XP in the same fashion. While Stars are temporary and are zeroed out every week, your XP lasts 10 weeks and goes through depreciation as time goes by. The calculation of XP is done automatically by our servers, and if any global problem related to it arises, all Artists will be informed through email.
You can always see the amount of XP and Stars you have by visiting your Artist Hub, and you can assume that those are the correct values for those resources. See also: Help Article: "How can I access the Artist Hub?".
- Only the number of Stars/XP displayed at the Artist Hub should be taken as official, and Sessions Support is not able to review any custom calculations you perform regarding these resources.
