Thanks. Do people with live accounts also get this issue?

[IG graphics not working properly]

I have a demo account. Over the last two weeks the IG graphics does not work properly. The graphs do not update and remains stuck at the previous day level of the share price although the deal ticket do update throughout the day. Depending on which interval I select, the graphs sometimes do update but the moment I select a different interval they collapse again. Any ideas what could be the matter?
