Stock market USA closed

What is happening I can’t trade or sell

There should have been a notification in-app.

There is some technical issue and the engineers are trying to fix, in the meantime they have paused trading of US stocks (I don’t believe UK stocks are affected).

I hope the problem is resolved quickly. Stock prices are pulling back today, so this a great chance to top up well performing shares. It’ll be a shame to miss out cos of this technical problem
