Ape Apps

Hey. Ive been away for some months and started to play again. But suddenly I cant trade at all so my economy is totally screwed.
Im online and logged in. I tried windows app and browser version too with the same effect.
I can open GBT and I see live prices at first. But when I try to sell or buy it will vanish and it says "there are currently no contracts available for sale".

Any help?

Am I able to do a trade only once a irl day?

Hey, I logged in after couple of months, logged in into an account too. Everything went well I was able to use GBT, but after one trade it started to show some error messages but I could see the menu on the left. Now the menu completely disappeared too..

Is there any option how to see whether im online or not?
