Identified - We've identified a bug in a recently shipped version of our javascript web SDK, around our surveys product. This seems to have had minimal impact on user site functionality, but is resulting in hugely inflated rates of exception capture for teams using our error tracking product. We're currently working to release a fix, and identifying impacted users to refund any exceptions captured as a result of this error.

If you see elevated rates of exceptions captured with:
Type: TypeError
Message: e.persistence.isDisabled is not a function

and are billed for these exceptions, please contact support, with product are "Error Tracking".
