Privacy, Data & Troubleshooting
Troubleshoot common issues
Most problems come down to which Google account Chrome is using, or the script's "Who has access" setting. Start here.
"Couldn't reach your calendar bridge"
Make sure Chrome is signed in to the Google account that has your calendar, then click Get my key and check your script opens without an error. If you use several Google accounts in Chrome, Google may pick the wrong one; try a Chrome profile that only has this account.
"Get my key" works but "Load my calendars" can't connect
Your script is probably set to Only myself (or Anyone within your organisation on a work account). Those rely on Google's sign-in cookies, which Brave Shields, Safari and Chrome's "Block third-party cookies" setting block. In Apps Script, go to Deploy → Manage deployments, click the pencil, change Who has access to Anyone, choose Version: New version and deploy. The URL and your key stay the same. On a work account where "Anyone" isn't offered, allow third-party cookies for [*.]google.com instead — see the Workspace guide.
"Key doesn't match"
Click Get my key and paste the key it shows. Keys change when you click Make a new key.
Deploy is greyed out or the app is blocked
On a work or school account, your admin may block Apps Script or limit who can use web apps. Ask your IT team, or use a personal Google account that can see your calendar.
No calendars listed
Next Up sees the same calendars listed in Google Calendar under "My calendars" and "Other calendars". Subscribe to a calendar there first, then click Load my calendars again.
No sound
Chrome keeps a page silent until you click it once — click Turn sound on when it appears. Also check Play a sound when each alert starts is ticked and the volume isn't at 0%.
Flashing is too much
Turn off Flash the page during alerts, or click Stop flashing during an alert.
Changed the script?
Use Deploy → Manage deployments, click the pencil, set Version: New version and deploy. That keeps the same URL. A new deployment creates a new URL, which you'd need to paste into Next Up again.
Settings gone
Settings are saved in your browser, separately for each Next Up window and tied to where the file is saved. If you move or rename the file, switch browsers, or clear browsing data, connect again — your script and URL still work. To update Next Up without losing settings, replace the old file with the new one in the same place and with the same name.
