Currently script seems to not work for tracking but still kind of works between refreshes.
update, it has started to work again... I have no idea why it stopped or what made it work.
When the script is exhibiting that type of functionality, it's typically an issue with the indexed DB within the browser. Typically the object stores weren't loaded or have otherwise gone missing, such that the database does technically exist, but none of the data can be retrieved from it. This causes the promise from the indexed DB call to return successfully, so the script proceeds as normal but there's no data. Not entirely sure why it happens, but if it doesn't resolve naturally, as in your case, you can delete the indexed DB from the developer tools and import a backup. Downside is that once it happens, if it doesn't resolve naturally, you won't be able to export a backup.
