ever since loading iOS8, I've been having random issues with my iMessage. on my phone i receive using my phone number and email, on my computer via email only and iPad via email only. handoff on all 3 devices are OFF. every now and then, i keep getting iMessages from my wife on both my iPad and my phone as if they were sent via email address. she said she's sending it via number, and i know it is since I'm the one starting the conversation from my phone which is set to send as my number. we don't share an apple ID, she was home on wifi with my iPad near, i was at work so i don't think its a wifi/handoff issue. it seems like iMessage is randomly messing up. I've switched iMessage off on both devices and back on again to see if it helps. on a side note, i was having a conversation with phone numbers with a coworker via phone numbers on our phones and he said one of my messages, mid conversation, came in under a different convo as my email address sent it. is there an iMessage bug where it decides to switch the caller ID from number to email? i don't need all of these messages ending up unnecessarily on my iPad.
