Hello,
I'm using Jira 6.1.1 (build 6155) server edition.
when adding text gadget with simple html (simple table with font elements).
when running with Microsot Edge, in some point the gadget stop to be accessible and I get the message: "This gadget was uninstalled by the administrator" and I have to delete the gadget.
After adding new text gadget, the first time when I add the html code - all looks fine. after page refreash - same error.
Needless to say, all this time the dashboard works properly on Chrome & Firefox
