I'm not sure if it's related to latest AGO update, but shortly after the update my publicly shared survey123 started prompting for login.
The survey was built with survey123 connect. It uses a submission URL that points to publicly share hosted View. The Hosted source layer is not shared publicly. The login prompt window references an itemID of hosted source layer, implying that it is not shared. But it should not be share. If I share the Hosted source layer publicly then the login prompt goes away. I fill like I'm missing something. Perhaps there are some new settings after AGO update that I need to check?
Anyone else ran into the same issue recently?
