Ember Travel Mug pop lid shoots hot coffee when opened

Anyone else experience this? The mug with the lid on and closed is airtight. Since the lid closes by pushing down and then springing up, it not only pushes air out but the heating of the coffee cubicles up pressure. The pressure is definitely what causes it. To prevent it I have to loosen the lid before opening it.

I’m on my second lid (first one broke) and it still occurs, so I’m surprised I have not seen more complaints about this.
