My Experience and a little suggestion

thank you because I have been given the opportunity to take the Alex Lab Foundation tesnet, now I want to give feedback regarding what I have done, I have bought on the books order but why do the open orders take about 5-10 minutes to come out and I do the same thing again and for about 10 minutes the history of the open order hasn’t come out either. maybe that’s the only problem, and I want to add. I’ve been looking for it but can’t find it, where is the button to change the theme? like white/black?

Thanks for the feedback. We will take it into consideration.
