My iPad and iPhone don't seem to want to Handoff text messages
I have an iPhone 7, iOS 10.3.3 and an iPad model MC954LL/A, iOS 9.3.5. I don't always see my texts on both devices. Following the instructions for setting up Handoff I don't see a place to turn on Handoff.
Some texts show up on both devices and others do not. I don't see a pattern. Am I missing something or are my 2 devices not compatible because of the different iOS versions? The iPad can't use any version later than theone on it now.
Thanks,
John
