@dry-elephant-14928 I tried to reproduce the issue with that example, but no luck. Plus, I forgot to note down the session id when it happened before. Just so you know, I'm using the javaScript sdk and for the past two days, it's been smooth - pretty much since we upgraded our plan last Friday. Before that, it happened pretty often. I'll definitely give you a shout if it comes up again. Btw, could this be related to any updates or deployments on your end? Because of 12 hours difference, your night-time deployments could be same as our working hours. Just a thought!
