Hi @Barbara70 !
Well that is soooo frustrating. Can you take a screenshot of what the calendar looks like on your laptop and post here? Other hosts might have some ideas as well. In the meantime...a few things to try:
Use a Different Browser
if using Google Chrome, try Firefox. You can also clear your cache/cookies/history in the browser.
Log Out of Your Account - Log Back in
Try using your email address to login instead of phone number
Let us know how it goes!
