Multiple locations and sub users including agency account admin are unable to add elements to the email builder or move elements on the email builder, especially with google chrome.

We've cleared cache and cookies but the issue pursuits. We've used Safari and have had some luck but some users report that Safari also no longer works for adding or moving elements inside the email builder.

We've tried contacting support multiple times but their feedback is always that they aren't having the same issue or to clear cache which does not resolve the problem.
