SAP released a note 3411067 yesterday which asks to apply recommended patch versions in custom application. Now we have a custom branded MDK client app built using SAP MDK SDK version 23.4.0 and it uses SAP Cloud Foundry runtime. We are using SAP on-premise IDM system as a thirt-party IdP for authentication to the app. I want to know if we have to make any changes pertaining to the note as mentioned above.
Since your app is running on the MDK mobile client, no changes are required on your side.
For the MDK web applications, we have just released MDK web runtime 23.8.5 patch, updating the appRouter version. There is no action needed by customers for their running MDK web apps.
