Collection: SMS Reminder for Shopify → Troubleshooting
SMS Reminder relies on your Google Calendar to hold appointments and block busy times. If bookings aren't showing up or times aren't blocking, re-syncing the connection fixes it in most cases.
Re-sync your calendar (the quickest fix)
Go to smsreminder.co and log in with your Google account.
Click your name in the top-right corner.
Select Synchronize Calendars from the dropdown.
This refreshes the connection and brings your calendar up to date.
Bookings aren't syncing to your calendar
Run Synchronize Calendars (above).
Make sure you're logged in with the Google account that holds your appointments.
Syncing is near-instant, but give a new booking a moment to appear.
"Can't connect" or a 403 / access error
When you log in with Google, accept all the permissions it asks for — if calendar access is skipped, nothing can sync.
If you're on Google Workspace and it's blocked, your workspace admin may need to allow the app before you can connect.
Busy times aren't blocking availability
Make sure the calendar with your commitments is connected and selected. Two-way sync then blocks those times automatically.
Your primary calendar is free; syncing additional calendars needs a paid plan.
Google keeps emailing calendar invitations
That's a Google Calendar setting, not the app — Google emails guests added to an event. You can adjust it in your Google Calendar event/notification settings.
