Fixed it in a REALLY ugly way, but I’ll post it here nonetheless if someone is searching for a quick temporary solution to the issue.
If the “started_at” is based on today, simply write:
var startDate = DateTime.UtcNow.ToRfc3339String().Replace(“+00:00”, “Z”);
Again, this hurts me to look at, but for now it’ll have to do I’m afraid.
Thanks again for your help Barry, hope you have a fantastic day <3
