Glad I’m not the only one. 
I’m also seeing a bunch of lines in the logs around the batch.js file–notably this one:
Failed to run init function: TypeError: removeOldAnalytics is not a function. (In ‘removeOldAnalytics()’, ‘removeOldAnalytics’ is undefined)
function () {
determineStorageKey();
setTimeout(bulkPublish, 500);
removeOldAnalytics();
}
I’ve opened a support ticket as well. I read in another post that it could be CDN. However, I have tested all of the CDN links that I use and they all come up just fine in the browser. If anyone has a resolution that I missed, please let me know–or us since I’m not the only one having issues.
