I have been trying, with little success, to load the Zephyr plug-in for JIRA Cloud. The load process is timing out - I am not otherwise getting any error messages. In the two hours since I started, I have managed to briefly get the plug-in to load once, but then after I viewed an Issue, going back to the plug-in failed again. I've checked the obvious reasons and the licence hasn't expired. Is there a known issue that I haven't seen yet? (PS: I'm a humble user, not a tech expert...)
