So I have a ego-cc, earlier today while I was using it, it worked just fine I noticed a bit of a sizzle and I'm guessing it's the juice that's being heated also while I was vaping I noticed like a bubble sound. Also didn't think much of it. About 3 hours later I picked it up to use it and noticed the taste, I have Blue Hawaiian flavor by the way, it now taste like a burnt flavor. Earlier it was rich in sweet flavor and not anymore. Any idea what it might be or what I can do? I'm very new to this. Sorry if I'm posting this in the wrong area.
