Hi @lrmakode. I was not able to reproduce this issue. Is your app a native Obj-C/Swift app? Can you provide a screen shot of the white screen you are seeing?
Hi @gastaffo our app is Obj-C app, please find attached video in the following video issue is reproduced.

in the following video issue is not there as user is asked for authentication.

Hi @lrmakode. Ok looks like we aren't giving UI control back correctly. Can you send logs from the device? You can bring up the diagnostics console by going to the app in the settings panel Microsoft Intune -> Display Diagnostics Console.
Also does your app do any swizzling at start up?
Hi @gastaffo please find logs attached. we are not using swizzling our iOS app.

let me know if anything else is required, if you want I can send the logs for the case in which issue is not reproduced.
Hi @lrmakode. Could you repro the issue again with verbose logging enabled? To enable verbose logging add the key "VerboseLoggingEnabled" to YES in the "IntuneMAMSettings" dictionary of the apps info.plist
Hi @gastaffo please find attached verbose logs with verbose logging enabled.

Hi @lrmakode. We aren't noticing anything out of place in the logs. It would be best if we could start an support ticket. To do this go to https://endpoint.microsoft.com/#home "Troubleshooting + support" -> "Help and support" -> "Intune".
Also another question, is the app linking to MSAL/ADAL before being wrapped?
Hi @gastaffo, Thanks for the help we have raised issue at Microsoft support and to answer you question we are not using MSAL or ADAL in our app.
Issue has been raised with internal support. No longer communicating on this thread. Closing issue.
I am also facing this issue ... Have you found RCA and the fix
@iit2008047 Could you provide logs from your repro like above? With the verbose key enabled.
