You have a mashup to show an external website embbeded in a Cloud for Customer screen. It works fine when accessing the system via browser, however when accessing the system via mobile app you receive the warning message: "You are using an outdated or unsupported browser and may experience some problems."
SAP Cloud for Customer
The site which is being loaded has a validation to check the browser compatibility based in the user agent (browser name identifier). The C4C app use the embeded web-view of the mobile device, however the user agent name is the name of the app and not the name of the browser (iOS Safari, Chrome, ...).
If you would like to avoid this kind of warning message you should ask to site developer include the Cloud for Customer user agent identifier "Cloud4CustEx"in the list of compatible browsers.
