My iPhone and iPad are both running iOS 11.2.5, have Wi-Fi, Bluetooth and Handoff turned on and airplane mode turned off, are signed into the same iCloud account and connected to the same Wi-Fi network and are right next to each other, but still I can’t get universal clipboard to work. I’ve tried signing out of and back into iCloud on both devices and turning them both off and on again. I briefly managed to get text copied from my iPhone to paste on the iPad, but not the other way around, but now that’s stopped working again. I have also tried copying between my iPhone 7 and iPhone 6, but that doesn’t work either. I don’t think handoff is working generally, but I’ve only had my iPad for a few months and I don’t think it’s been working for any of that time, so not sure exactly what I’m supposed to be seeing. If I’m supposed to be seeing one device’s apps in the other device’s app switcher, I’m not getting that. Any ideas why this might not be working? Does it require a Mac to be connected to the same iCloud account? I’m trying to use this with just iOS devices.
