Hi ​@Jarnobroekkamp, 

Hopefully you figured out a fix for this by now.  But occasionally, if you see these problems, you may want to try logging in/out of your account (in a separate tab).  And, if you have multiple Klaviyo Accounts, make sure you’re logged into the correct account.  For example, if you have a separate tab and switched account, you need to switch back.  

If you see this problem again, I recommend contacting Klaviyo support as this seems like a technical issue on Klaviyo’s side.
