Missing Time Travel feature on Apple Watch in OS3

I am fairly "late to the game", but since no answer has been accepted yet, my input might still be useful:

• the "meeting highjacking" you describe in your question is fairly well known with Exchange and the iOS calendar app; in fact it can be even worse where simply accepting an invite on your phone may make you the "owner" of the meeting; this seems to happen more often the larger the number of meeting attendees gets. This issue is so severe that in my company we discourage people from accepting meeting invites from their phones.
• as for the "butchered description" you describe in your answer: this, too is a well known issue between Exchange and the iOS calendar. iOS 8.3 supposedly fixed it, but since those cut off notes do not happen all the time, we do not have enough data yet at work to say for sure.

I have Iphone 4s and this happens once or twice a year.I ignore signing in my emaail account when asked.This time I signed in to my account as if I wanted to send to my Calender and the plus sign turned back to red and now works.I don't normally sync to my account.I just keep info on phone.
