I have a SmartSheet account in a large organization and I'm trying to share a workspace to the higher-level leadership, but for some reason for certain team members, it won't share. I open the Share workspace box and add in emails, and some will give me the confirmation that the email was sent, but others when I click Share, I'll get the spinning dots on the button and then nothing, where it should give me that confirmation that and email was sent. I've checked the email addresses countless times, and they are correct. Any reason this is happening for some folks and not others?
