"I can't open this invite" / missing token

NimbleCal invite links include a one-time token in the URL fragment (often shown as #token=...). That token is required to view the invite and RSVP.

If you copy/paste only the base URL (without the token), NimbleCal cannot load the invite details.

Fix:

  • Open the invite from the original email, or
  • Ask the organizer to resend the invite.

"Switch accounts"

Some invites are restricted to the NimbleCal account that was invited. If you're signed into a different account, the app will block the RSVP to protect access.

Fix:

  • Sign out, then sign in with the email address that received the invite.

Emails not arriving

Fix:

  • Check spam/junk folders.
  • Ask the organizer to resend the invite.
