Public web app requires login

[salmonjmar]

Hi and thank you in advance for any help you can offer. I just tried to replicate a web app I created 6 months ago with different data and every time I get a login window. I checked to see if any layers or files were not shared publically, checked the security setting to allow anonymous access, and I even tried to create a web app using only an ESRI base map and it still asked for login. This leads me to believe that the layers are not the problem.  This is the link to the web app: https://martin-salmon.maps.arcgis.com/apps/StoryMapBasic/index.html?appid=53adf2dbd72f4e58b5ccff3eab...

The 6-month-old web app is still working. Could it be that the 2021 update to AGOL is creating this problem?

many thanks for your help.

Martin

Hi I'm also having the same issue has anyone worked out where you turn off this 'show developer base maps options'? Thanks!

I'm having the same issues and noticed that it is the basemaps in the "new" Map Viewer that is causing the problem. If I create a web map with just a basemap in the "new" map viewer then it requires a login. If I open the same map in Map Viewer Classic, change the basemap, then I can share it just fine. I can even open the web map created in Classic with "new" map viewer and it will also open fine.

For anyone else struggling with this issue... I resolved the problem by enabling the ability to allow anonymous access to AGOL/Portal. This setting was overriding the public basemap sharing settings.
