Hi all, any help appreciated.
I have an existing Survey123 form published with Survey123 connect (using AGOL). When I make changes to the XLSform which change the data schema, I get the normal warning dialogue box which says "The existing feature service is not compatible with the survey." When I check the slider saying "I understand the existing feature service will be deleted" and Publish, all seems to work.
However I now have two matching feature services in AGOL with the same name. One has the old data (collected prior to the re-publish) and it stays static. The other one has all data going forward. The only difference I can see is the data itself and the modified date. I have scoured the help documents and I don't think this is by design, but perhaps it's a new release feature? I can see why it would be good in concept, but it's causing issues for me, which makes me think it's a bug.

This has happened to me twice now. Any thoughts welcome, thank you.
