The IG trading app I think has breakdown for around 1 year since the beginning of 2020, and I cannot login the app and trade for so much long time. No other operations could be down since then and my money was therefore blocked in their account. I used to try contact its IT support team, however, they were useless and cannot give a reasonable reason why I cannot use the app anymore. Therefore I have reasonable reason to assume that there might something wrong with the company itself.
