Has anything changed recently in the sandbox regarding challenges?  Our code that worked a month ago now does not.  Famous last words..."nothing has changed at our end", but challenges no longer appear.

We're using .Net Sdk.  Package looks good and has challenge in there.  We tried both SMS and Q&A.  We are using signing Url with loginToken, not session token. Did not see anything is May release notes that sounds like a change in this area.

Any ideas?

Likely we'll find a dependency changed in our codebase...but we've already spend a lot of time looking, and it would be comforting to know the SDK/Platform is not the issue. 

Thanks in advance for your help. 

Thanks.  Sent.

Thanks Duo...for the benefit of the group, the issue was our package had a single signer.  When email of that signer matches the sender in account setup, the challenges are by-passed. 

In our case, we had changed the package and account settings for test purposes, not knowing of this behavior.

Thanks again Duo for your super-fast assistance. :-).
