hey Penny,
I am sorry this is happening for you. The “try our free trial” banner should not show again after you dismiss it, but we have found that in certain cases it does not save the “dismiss” message.
Unfortunately this is not built into our code, but rather in the 3rd party code of our license provider that we use under the hood.
But I am going to build in a setting that forces the banner to never show. This will be in the next release.
