The 2 problem ones are an Iphone 5 and an Ipad. Yes, we have logged them out and logged back in, but they are still not seeing the share and the 2 names are on the "share" list but greyed out.
I have 2 users I have been trying to share a notebook for 2 months now. I keep "sending' and they are not getting an email and this notebook is not showing up in their Evernote. I have tried deleting and re-adding - still nothing. I have access to one of the email accounts and there have been no messages from Evernote sent. When I go to "sharing", they are there, however, their names are grayed out.
