I have had to (unfortunately) connect through DXB many a times and as many will tell you it’s not the best airport to try and make a connection in. If you have 2 hours (assuming everything is on schedule) it's just enough time. If I were you I’d find my gate first, head over there, and then spend time at whatever duty free shop is closest to your gate. Alternatively you could stop at duty free on the way to your gate if you find a store, and are making good time to your departure gate.

EK is notorious for closing the door 20 minutes before departure no matter what class of service you’re in, and even if the aircraft isn’t pushing back. They don’t care what your excuse is for not being there 20 minutes before departure. To add insult to injury front line employees don’t have much power, and will follow the rulebook to the T because most GA’s come from very poor countries and they don’t wanna take any risk losing their job. God could come down himself and stop you from getting to your gate and EK staff won’t care. Even when it is beyond your control to get to the gate, they don’t care.

So my first priority would be to make sure you get to your gate, or get close to your gate.
