Should I file a support case for this?

I filed a case asking for further details. The warning message went away.

I’ve just had an upgrade notification for the File Drag and Drop bundle which says it’s upgrading to support the latest Ext JS, will probably resolve the error you are getting: Support for the latest Ext JS • The new version of File Drag and Drop now supports the latest licensed Ext JS, leading to an improved overall performance.

I did just upgrade but the warning is still there

I received an email from support saying this has been resolved, and the banner no longer appears in my RP account.
