Im trying to send some keys to my balance to buy some gifts, and trying to withdraw some gifts from my inventory as well, but there is something stuck, I always end with the "Your maximum open tasks is reached. Please wait for some of them to expire." message, in both situations. I waited a couple of days hoping something would timeout and allow me to retry/complete those tasks, but this keeps occurring. Steam confirmation dialog in mobile always gives out an confirmation error for the dispenser offer, and the trade offer is still there. I then tried to refuse the offer, with the same effect, still stuck. I tested trading with a friend and had no problems confirming other trade offers. The only thing stuck is the last trade offer dispenser sent me for the keys.
