Ever wondered how many external choices can you have before Survey123 maybe chokes on you?
Well I am here to tell you that I have been consistently able to publish surveys with anywhere between 70K-120K rows/records in the External choices. Now before you start calling me names or brand me an outcast, I am myself not particularly proud of the fact that we had to do it but I had a unique situation where it had to be done and it does work with occasional failure. The survey app works fine too after the initial download (which can take a while - I've seen 15-45 seconds survey load time for 70K+ rows).
This is not something I will proudly promote but doing this is definitely possible if someone needs to do it in a pinch. I thought it was important to share this not-too-exciting achievement .
