Jira Software/ Jira Core v 7.3.6
Each time I click Edit on an issue or delete on an attachment the please wait icon appears and keeps spinning. Nothing else happens. I can press esc or refresh the browser then so it doesn't crash the browser but I can't access these functions and possibly others. It's not a Jira security issue. I've got the same issue on chrome, firefox or edge. Rarely it works. This has only just started happening and I haven't made any upgrades.
