I was having issues where I'd hear a crackle and then the audio would dropout as well. When that happened I could hear nothing but others in the session could still hear me. It was occurring in pretty much every session I joined. Happily, since the latest update it hasn't happened at all. I've done a couple dozen sessions since then, so I'd say this latest update fixed that particular issue. I'm running OSX 10.13.6 (High Sierra) on a 2016 15" Macbook Pro with a 1st generation Focusrite Scarlett 2i2 interface.
