Hi RobSverige, it should as long as they are all setup to sync. I use my O365 email, OneDrive across all devices including iOS, i even use my work email across my fold3 and s8 ultra with a work profile, works perfect, yes now an again if you have not used the app in a while on a device, give it a moment to sync first.
Beauty of Samsung work profile is one icon switches it all OFF or ON, unlike the ***** iPad.
