I’ve had a similar problem occur when there were more than 1 AnyChart widget on the page.
Are you able to replicate this issue on a blank page with just 1 AnyChart widget present?
blank page and only 1 AnyChart widget also has the same problem. version i am using is 9.11.1 and its the latest AnyChart widget available in the marketplace
i have the same problem. Did you ever find an answer?
