Hi,
We recently installed Update Rollup 10 in our development environment and we started getting the following alert message in our JavaScript WebResource.
“You have exceeded the maximum number of 200o characters in this field; it will be truncated”
However it allows us to save the web resource properly after we close (cancel) the popup.
