Hello,
I had a weird thing happen with a Survey123 submission: I'm testing out a a survey and when I hit the submit button, the icon just sat there and spun for an unusually long time. I went into the hosted layer data tab and found that over 10,000 records had been created. the submission was still spinning and when I refreshed the data tab on the hosted layer, I found that the count was still going up!

Letting the survey submit for about a minute resulted in 20k records. It wasn't a one-off, I tested again and the same thing happened.
I had previously constructed this survey for a referenced feature service where it behaved as expected. I created a hosted layer and basically copied the construction of the survey from the referenced to the hosted .xlsx.
Has anyone ever seen this before?
