So You set up a meeting and someone has proposed a new time (At least that's what the email says) but you don't see the new time on your desktop browser.
Below is the solution to problem
Workarounds:
1: View the mail with proposed new time in Gmail app on mobile phone
2: View the mail with proposed new time in Gmail Offline app: https://mail.google.com/ mail/mu/
