If you're not seeing all the calendars you have access to on your dashboard, here are some things to check.
If you have separate emails, perhaps a work email and a personal email, you may need to add a secondary email to your account in order to access all the calendars shared with you.
In a browser, log into your user account as normal. Go to your profile and check which email address is linked with your user account.
If you only have a personal email associated with your user account, you need to add your work email to access calendars shared with you through work. Follow these steps to add a secondary email to your account. You can add more than one secondary email address.
If you have a calendar link, but you don't see the calendar on your dashboard, take a look at the link.
There are two types of access links.
A shareable calendar link looks like this:

If it is a shareable calendar link, you'll need to add it to your dashboard manually. Follow these steps to do so on a browser or on the Teamup app.
