Our environment is using TC56 devices (Nougat) and Android Enterprise.
Since the AE agent upgraded to 13.6, we had to upgrade Surf to 14.2 version for it to continue working, but there's a catch.
When surf is upgraded to 14.2, or even installed as new on a factory reset device, it won't ask for all the authorizations it needs, it will ask for 2 of them, but when you launch surf (from surf:// in kiosk mode) you will get a flashing strobe mess and the app will remain stuck that way.
Manually granting the other permissions in app settings fixes it and surf works fine after that, but I think SOTI should be aware of that, since something's not right in that version.
Of course using Zebra devices we can (and will) use the appmgr to grant all the permissions on install, but this should be addressed imho.
Surf config is as basic as it can be : Fullscreen mode with no address bar and no startup menu, then kiosk is used to access chosen websites.
