Hi Yin, Yes, I'm aware of those constrains but I would argue that you can have multiple trials running at the same time; Just not on the same "base campaign". It is not explicitly mentioned in the documentation that this limitation is per campaign but it supported by:
1. It is possible setup multiple trials spanning the same dates in the UI (as long as they target different campaigns) 2. Multiple overlapping trials can be setup by using multiple API calls (as done in the example code) The 3 example operations above target *3 different campaigns *and they work/*get accepted if submitted individually* (inefficient and prone to rate-limits) and it does *not* work* if submitted **together*. If there were a constraint issue then submitting them individually shouldn't work, right? I would prefer not doing multiple API calls for each trial but, if you say that the service is working as intended, that is what I will have to do.
