There might be a situation that arises which requires you to disconnect and then reconnect Apple Calendar. This process requires a few extra steps that we’ve outlined below.
You’ll want to navigate to “Settings” while on the calendar select “External Calendars”
Select Apple and then tap the option to “Edit Visible Apple calendars”.

Lastly, tap “Disconnect calendar” to break the connection between Apple and Maple.
When you originally connected Apple Calendar you needed to create an App-specific Password for security. This first step in the process involves deleting the old password and creating a new one.
Tap ‘Connect’ in Maple to trigger the Apple Calendar connection screen to pop up.
Here you’ll want to tap the URL for App-Specific Passwords (as in the screenshot below)

This is going to direct you to an Apple page where you will then log in with your AppleID and Password.
Once you’ve logged in, you’ll want to navigate down to the “App-Specific Passwords” section.

You’ll want to find ‘Maple’ and then tap the little “-” icon (as seen above). This will kick off the process to revoke access. Please follow the prompts until access is totally revoked.
note: you might be asked to log with your AppleID and Password a few times here.
Now that you no longer have an App-Specific Password for Maple, you’ll need to create one to reconnect Maple and Apple.
