Hello @jnm and @Kal_Lam ,
Here is a (reduced) form demonstrating the problem:
MigTest02.xlsx (11.2 KB)
Neither the relevant clause nor the constraints are working as expected, on the test-links. (Tested with Preview and with Offline-URL)
But all works as expected (and in the past) in normal KoBoToolbox.
Furthermore, I was surprised, that the problem is the same now if we test (Preview) with ODK Online validator. Is there already the test version?
Kind regards
