Performance and loading issues

Last reviewed May 14, 2026

Most issues are quick to fix. Start from the top and stop when things look normal again.

1. Refresh the page

Try a normal refresh first.

If that does not help, try a hard refresh:

  • Mac: Cmd + Shift + R
  • Windows/Linux: Ctrl + Shift + R

2. Close extra tabs

If you have NimbleCal open in multiple tabs, try closing all but one and refresh.

3. Check your connection and any blockers

  • If you're on a captive portal (hotel/plane Wi-Fi), sign in to the network first.
  • If you use strict content blockers, try disabling them for app.nimblecal.com.

4. Clear browser storage only as a last resort

Clearing browser storage removes local calendar data.

Before you wipe anything
Clearing storage removes your local copy. Export first so you have a backup: Export calendars as ICS.

If sync is healthy, NimbleCal can usually re-download your encrypted data after you sign in again.

Still stuck?
